# This Makefile builds native Windows tcc for both 32 and 64 bits generator.
# It requires Cygwin 64 and gcc to bootstrap a first tcc version which is used
# 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.
