In contrast to this no error will occur + * if the lib is linked to a C-program. + * + * Further info on FPUs: + * For x86 and x86_64 CPUs we have to consider two FPU instruction sets. + * The math co-processor i387 (aka 8087 or x87) set introduced with the i386 + * and SSE (Streaming SIMD Extensions) introduced with the Pentium3. + * Both of them have separate control-registers (x87: FPUControlWord, SSE: MXCSR) + * to control FPEs. Either has (among others) 6bits to enable/disable several + * exception types (Invalid,Denormalized,Zero,Overflow,Underflow,Precision). + * Those exception-types must all be masked (=1) to get the default C behaviour. + * The control-registers can be set with the asm-ops FLDCW (x87) and LDMXCSR (SSE). + * Instead of using assembler code, we can use Set8087CW() provided by delphi and + * FPC to set the x87 control-word. FPC also provides SetSSECSR() for SSE's MXCSR. + * Note that both Delphi and FPC enable FPEs (e.g. for div-by-zero) on program + * startup but only FPC enables FPEs (especially div-by-zero) for SSE too. + * So we have to mask FPEs for x87 in Delphi and FPC and for SSE in FPC only. + * FPC and Delphi both provide a SetExceptionMask() for control of the FPE + * mask. SetExceptionMask() sets the masks for x87 in Delphi and for x87 and SSE + * in FPC (seems as if Delphi [2005] is not SSE aware). So SetExceptionMask() + * is what we need and it even is plattform and CPU independent. + * + * Pascal OpenGL headers (like the Delphi standard ones or JEDI-SDL headers) + * already call Set8087CW() to disable FPEs but due to some bugs in the JEDI-SDL + * headers they do not work properly with FPC. I already patched them, so they + * work at least until they are updated the next time. In addition Set8086CW() + * does not suffice to disable FPEs because the SSE FPEs are not disabled by this. + * FPEs with SSE are a big problem with some libs because many linux distributions + * optimize code for SSE or Pentium3 (for example: int(INF) which convert the + * double value "infinity" to an integer might be automatically optimized by + * using SSE's CVTSD2SI instruction).

+ * An IPath represents a filename, a directory or a filesystem path in general.

+ * Internally all paths are stored with the same path delimiter (PathDelim)
+ * and encoding (UTF-8). The transformation is already done AT THE CREATION of
+ * the IPath and hence calls to e.g. IPath.Equal() will not distinguish between
+ * Unix and Windows style paths.
+ *
+ * Create new paths with one of the Path() functions.
+ * If you need a string representation use IPath.ToNative/ToUTF8/ToWide.
+ * Note that due to the path-delimiter and encoding transformation the string
+ * might have changed. Path('one\test/path').ToUTF8() might return 'one/test/path'.
+ *
+ * It is recommended to use an IPath as long as possible without a string
+ * conversion (IPath.To...()). The whole Delphi (< 2009) and FPC RTL is ANSI
+ * only on Windows. If you would use for example FileExists(MyPath.ToNative)
+ * it would not find a file which contains characters that are not in the
+ * current locale. Same applies to AssignFile(), TFileStream.Create() and
+ * everything else in the RTL that expects a filename.
+ * As a rule of thumb: NEVER use any of the Delphi/FPC RTL filename functions
+ * if the filename parameter is not of a UTF8String or WideString type.
+ *
+ * If you need to open a file use TBinaryStream or TFileStream instead. Many
+ * of the RTL classes offer a LoadFromStream() method so ANSI Open() methods
+ * can be workaround.
+ *
+ * If there is only a ANSI and no IPath/UTF-8/WideString version and you cannot
+ * even pass a stream instead of a filename be aware that even if you know that
+ * a filename is ASCII only, subdirectories in an absolute path might contain
+ * some non-ASCII characters (for example the user's name) and hence might
+ * fail (if the characters are not in the current locale).
+ * It is rare but it happens.

+ * This interface needs the cwstring unit on Unix (Max OS X / Linux) systems.

+ * Due to a compiler bug in FPC <= 2.2.4 reference counting does not work
+ * properly with interfaces (see http://bugs.freepascal.org/view.php?id=14019).
+ *
+ * There are two (probably more) scenarios causes a program to crash:
+ *
+ * 1. Assume we execute Path('fail').GetParent().ToUTF8(). The compiler will
+ * internally create a temporary variable to hold the result of Path('fail').
+ * This temporary var is then passed as Self to GetParent(). Unfortunately FPC
+ * does already decrement the ref-count of the temporary var at the end of the
+ * call to Path('fail') and the ref-count drops to zero and the temp object
+ * is destroyed as FPC erroneously assumes that the temp is not used anymore.
+ * As a result the Self variable in GetParent() will be invalid, the same
+ * applies to TPathImpl.fName which reference count dropped to zero when the
+ * temp was destroyed. Hence GetParent() will likely crash.
+ * If it does not, ToUTF8() will either return some random string
+ * (e.g. '' or stupid stuff like 'fhwkjehdk') or crash.
+ * Either way the result of ToUTF8() is messed up.
+ * This scenario applies whenever a function (or method) is called that returns
+ * an interfaced object (e.g. an IPath) and the result is used without storing
+ * a reference to it in a (temporary) variable first.
+ *
+ * Tmp := Path('fail'); Tmp2 := Tmp.GetParent(); Tmp2.ToUTF8();
+ *
+ * will not crash but is very impractical and error-prone. Note that Tmp2 cannot
+ * be replaced with Tmp (see scenario 2).
+ *
+ * 2. Another situation this bug will ruin our lives is when a variable to an
+ * interfaced object is used at the left and right side of an assignment as in:
+ * MyPath := MyPath.GetParent()
+ *
+ * Although the bug is already fixed in the FPC development version 2.3.1
+ * it will take quite some time till the next FPC release (> 2.2.4) in which
+ * this issue is fixed.
+ *
+ * To workaround this bug we use some very simple and stupid kind of garbage
+ * collection. New IPaths are stored in an IInterfaceList (call it GarbaegeList)
+ * to artificially increase the ref-count of the newly created object.
+ * This keeps the object alive when FPC's temporary variable comes to the end
+ * of its lifetime and the object's ref-count is decremented
+ * (and is now 1 instead of 0).
+ * Later on, the object is either garbage or referenced by another variable.
+ *
+ * Look at
+ * MyPath := Path('SomeDir/SubDir').GetParent()
+ *
+ * (1) The result of Path('SomeDir/SubDir') is garbage as it is not used anymore.
+ * (2) The result of GetParent() is referenced by MyPath
+ * Object (1) has a reference count of 1 (as it is only referenced by the
+ * GarbageList). Object (2) is referenced twice (MyPath + GarbageList).
+ * When the reference to (2) is finally stored in MyPath we can safely remove
+ * (1) and (2) from the GarbageList so (1) will be freed and the ref-count of
+ * (2) will be decremented to 1.
+ *
+ * As we do not know when it is safe to remove an object from the GarbageList
+ * we assume that there are max. GarbageMaxCount IPath elements created until
+ * the execution of the expression is performed and a reference to the resulting
+ * object is assigned to a variable so all temps can be safely deleted.
+ *
+ * Worst-case scenarios are recursive calls or calls with large call stacks with
+ * functions that return an IPath. Also keep in mind that multiple threads might
+ * be executing such functions at the same time.
+ * A reasonable count might be a max. of 20.000 elements. With an average length
+ * of 40 UTF8 chars (maybe 60 byte with class info, pointer etc.) per IPath
+ * this will consume ~1.2MB.
