# This makefile is for cross-compiling to a windows binary from a linux host
#
# It's ugly, in that it's just a copy of Makefile with the ldflags and cflags
# hardcoded and the install actions removed. 
#
# With this cross-compiler (mingw package in ubuntu) the order of -l gcc
# options matters, so the $(ldflags) was moved to the end of the link script
