updated the build system to avoid file duplication : - All "common" ANSI files were moved to "freetype2/config" - The modules list is in "config" now (instead of config/<system>") - All system-specific configuration Makefiles have been renamed. E.g. "config/win32/Makefile.gcc" is now "config/win32/w32-gcc.mk" - Updated "config/freetype.mk" and "config/modules.mk"
