Poly/ML for Isabelle
====================
This compilation of Poly/ML 5.4 is based on the official sources from
http://www.polyml.org with the following patch from the SVN (which is
also part of the fixes-5.4 source tree):

Fix to arbitrary precision emulation for X86. A GC during emulating
an operation could cause the stack to move resulting in the result of
the operation not being stored into the result register.

The included build script is used like this:
./build src x86-linux --with-gmp
./build src x86_64-linux --with-gmp
./build src x86-darwin --without-gmp
./build src x86_64-darwin --without-gmp
./build src x86-cygwin --with-gmp
The multi-platform directory layout for executables and shared
libraries accommodates the standard ML_HOME settings for Isabelle.
Also note that the separate "sha1" library module is required for
efficient digesting of strings according to SHA-1.
