Hash : 63408a12
Message : include/freetype/internal/internal.h: Fixed header inclusion macros to use direct definitions. This is the only way to do these things in a portable way :-( The rest of the code should follow shortly though everything compiles now. * builds/compiler/intelc.mk, builds/compiler/watcom.mk: New files. * builds/win32/detect.mk: Added support for the Intel C/C++ compiler, as well as _preliminary_ (read: doesn't work!) support for Watcom. Also added a new setup target. Type "make setup list" for a list of supported command-line compilers on Win32. * src/base/ftdebug.c: Added dummy symbol to avoid empty file if conditionals are off.
