### For Win32/Win64 version cross-compilation via MinGW
### compiler suite under Linux/Unix

#
# This Makefile assumes that you have MinGW installed under /usr
# the way Debian MinGW packages do. It also assumes that you have
# built/installed SDL2 and PDCurses 3.9 (SDL2 variant) under
# /usr/local (not /usr!) in similar fashion.
#
# For differing configurations you will have to either edit this
# file or alternatively provide make parameters, e.g.
#
# make -f Makefile.cross-mingw MINGW=64 BINTOOL_PREFIX=foo-bar-zoo
