# Script to help build the Windows (mingw32/mingw64) distributions from
# cygwin.
#
#
# This script can be invoked as 
#   mingw-build
#   mingw-build mingw32
#   mingw-build mingw64 
# from the top-level Yices source directory
#
# The first form builds the static and binary distributions for
# both Windows 32bits and Windows 64bits.
# The second and third forms do it for only 32bit or 64bit Windows
#
# Prerequisites for this to work:
# - must be on a cygwin bash
# - visual studio must be installed
# - Yices must be configured for both mingw32 and mingw64
# - we must have two versions of libgmp-10.dll (one for
#   mingw32 and one for mingw64)
#

#
# check arguments
#
