#
# Makefile for Hercules S/370, ESA/390 and z/Architecture emulator
# modified to build hercules under windows (VB)
# modified to build external GUI compatible version under Windows (Fish)
# modified to be useful (hopefully) for Linux AND windows (VB)
# Added LINKMAP option (Fish)
# Support for version >= 1.3.3 of Cygwin = built-in pthreads (Fish)
# Added Malcolm Beattie's dasdcat program (rbowler)
