# Changes 27 July 2005 by Angus Leeming to enable the Makefile to
# work out of the box on both *nix and Windows machines under
# the MinSYS environment.
#
# The Makefile can also be used unaltered to build a Windows executable
# from a Linux box if make is invoked as:
# $ make EXEEXT='.exe' CC='i386-mingw32-gcc'
