# Invoke this makefile from a DOS-prompt window via:

#	make -f Makefile.mingw32

# This makefile assumes zlib has already been built or downloaded and is in
# a subdirectory at the same level as the current subdirectory (as indicated
# by the ZPATH macro below).  Edit as appropriate.
#
# Note that the names of the dynamic and static zlib libraries used below may
# change in later releases of the library.  This makefile builds statically
# linked executables, but that can be changed by uncommenting the appropriate
# ZLIB line.
