# This file allows us to create windows
# 32 and 64 bit binaries instead of binaries
# for the compiling host. It assumes that the
# GNU compiler suite is the compiler for all
# three targets.
#
# TARGET is a bit of a misnomer. The goal is
# really to allow different toolchains to be used
# to build the system.
#
# Supported TARGET values include:
#
# mingw32
# mingw64 (except c++, so mostly not)
# llvm
# clang
#
# Typical use is to say at the toplevel:
# make
# or
# make TARGET=mingw32
# or
# make TARGET=mingw64
#
# But you can also just set it here:
#
# TARGET=mingw32
