// -------------------------------------------------------------------
// 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.
