# Script to compile the Ampl Solver Library using cl/link. Why this approach?
# Well, we don't want to get into the business of creating (and maintaining)
# the full set of autotools source files for the ASL. This approach tries to
# leverage makefile.vc, which comes with ASL.

# To support VPATH builds, the strategy is to copy the sources to the build
# directory, build, and then erase the sources when we're done. Start by
# copying the sources.

# Do the build. CFLAGS specified on the command line (as a result of autoconf
# replacing ASLMAKEFLAGS) will override the specs in makefile.vc, ensuring
# that ASL is built with the same compiler flags as other code. It turns out
# that Gnu make always sets MAKEFLAGS to --unix, and nmake tries to process
# this, resulting in error U1065. Clear MAKEFLAGS to fix the problem.
