+// -------------------------------------------------------------------
+// Note on version comparison (for developers only):
+// -------------------------------------------------------------------
+// Delphi (in contrast to FPC) DOESN'T support MACROS. So we
+// can't define a macro like VERSION_MAJOR(version) to extract
+// parts of the version-number or to create version numbers for
+// comparison purposes as with a MAKE_VERSION(maj, min, rev) macro.
+// So we have to define constants for every part of the version here.
+//
+// In addition FPC (in contrast to delphi) DOES NOT support floating-
+// point numbers in $IF compiler-directives (e.g. {$IF VERSION > 1.23})
+// It also DOESN'T support arithmetic operations so we aren't able to
+// compare versions this way (brackets aren't supported too):
+// {$IF VERSION > ((VER_MAJ*2)+(VER_MIN*23)+(VER_REL*1))}
+//
+// Hence we have to use fixed numbers in the directives. At least
+// Pascal allows leading 0s so 0005 equals 5 (octals are
+// preceded by & and not by 0 in FPC).
+// We also fix the count of digits for each part of the version number
+// to 3 (aaaiiirrr with aaa=major, iii=minor, rrr=release version)
+//
+// A check for a library with at least a version of 2.5.11 would look
+// like this:
+// {$IF LIB_VERSION >= 002005011}
+//
+// If you just need to check the major version do this:
+// {$IF LIB_VERSION_MAJOR >= 23}
+//
+// IMPORTANT:
+// Because this unit must be included in a uses-section it is
+// not possible to use the version-numbers in this uses-clause.
+// Example:
+// interface
+// uses
+// versions, // include this file
+// {$IF USE_UNIT_XYZ}xyz;{$IFEND} // Error: USE_UNIT_XYZ not defined
+// const
+// {$IF USE_UNIT_XYZ}test = 2;{$IFEND} // OK
+// uses
+// {$IF USE_UNIT_XYZ}xyz;{$IFEND} // OK
+//
+// Even if this file was an include-file no constants could be declared
+// before the interface's uses clause.
+// In FPC macros {$DEFINE VER:= 3} could be used to declare the version-numbers
+// but this is incompatible to Delphi. In addition macros do not allow expand
+// arithmetic expressions. Although you can define
+// {$DEFINE FPC_VER:= FPC_VERSION*1000000+FPC_RELEASE*1000+FPC_PATCH}
+// the following check would fail:
+// {$IF FPC_VERSION_INT >= 002002000}
+// would fail because FPC_VERSION_INT is interpreted as a string.
+//
+// PLEASE consider this if you use version numbers in $IF compiler-
+// directives. Otherwise you might break portability.
