# Name:    Makehead.cygwin
#
# Purpose: This file is used to customize operating system and installation
#          dependent features of the MX makefiles.  This version is customized
#          for Cygwin under Microsoft Windows.
#
#          Cygwin may be found at http://www.cygwin.com/
#
#          Note: MX will not compile under Cygwin unless Sun RPC development
#          libraries are installed.  For old versions of Cygwin, this
#          required that the 'sunrpc' package be installed.  Newer versions
#          of Cygwin require the 'libtirpc-dev' package instead.
#
# Normally, the only things that end users may have to modify in this file are
# the definitions of INCLUDES, LIB_DIRS, and LIBRARIES.
#

# command line, so we test for the existence of /usr/lib/librpclib.a

# command line, so we test for the existence of /usr/lib/libtirpc.dll.a
