#
# This Makefile builds native Windows tcc for both 32 and 64 bits generator.
# This makefile is adjusted from 'https://sourceforge.net/projects/wintcc/'
# It requires mingw64 (and static libs for dl and pthread) and wine installed on linux.
# by a second stage to compile tcc it self.
# Generated binaries do not require cygwin to run.
# You can launch 'tarball' target to build a tar.gz you can install on any
# Windows machines.
