#
#  Shared makefile for building the Allegro library. Requires GNU make.
#
#  Available options:
#
#     Environment variables:
#        DEBUGMODE=1        selects a debug build.
#        DEBUGMODE=2        selects a build intended to debug Allegro itself.
#        PROFILEMODE=1      selects a profiling build.
#        WARNMODE=1         selects strict compiler warnings.
#        STATICLINK=1       use static linking (MinGW32, MSVC, BeOS).
#        TARGET_ARCH_COMPAT optimize for the given processor while preserving backwards
#                           compatibility with older processors (GCC-based platforms).
#        TARGET_ARCH_EXCL   optimize for the given processor; this will cause the library
#                           to *NOT* be backwards compatible (GCC-based platforms, MSVC).
#        TARGET_OPTS        allows you to customize general optimizations (GCC-based platforms).
#        CROSSCOMPILE=1     cross-build under Linux (DJGPP, MinGW32).
#        ALLEGRO_USE_C=1    use C drawing code instead of asm (GCC-based platforms).
#        UNIX_TOOLS=1       use Unix-like tools instead of DOS tools.
#
#     Targets: 
#        default:           build library version, docs, and programs.
#        all:               build all versions and programs.
#        lib:               build a single library only, no programs.
#        programs:          build all programs
#        install:           install single library version.
#        installall:        install all library versions.
#        uninstall:         remove Allegro from system directories.
#        docs:              convert documentation from ._tx sources.
#        chm-docs:          generate additinal docs in CHM format.
#        clean:             remove object files.
#        distclean:         remove objects and executables.
#        veryclean:         remove all generated files.
#        compress:          compress the executable files (DJGPP, MinGW32, MSVC).
#        depend:            regenerate the dependency files.
