The `gcc' directory holds a copy of libffi from the GCC repository,
with extra files that are needed to configure it. Similarly, The
`libffi_msvc' directory holds a copy of the libffi version from the
CTypes project.
Note: libffi is maintained as part of the GCC code repository, but it
is still distributed under an LGPL-compatible license. CTypes is
under the MIT License.
========== gcc directory =============================================
The directory is synced from the GCC repository, revision 140226.
Our copy of libffi for PLT Scheme has been changed in a few small
ways:
Local changes:
* Removed libffi/testsuite directory (r8401)
* Removed testsuite mention in configure and make files (r8403)
* Recreated the libffi/configure with autoconf version 2.61 (r8412)
* Changed config/multi.m4 to allow in-source-tree builds, rebuild
libffi/configure (r8413)
* Removed +live_support in src/powerpc/darwin_closure.S so it builds
with Mac OS X 10.3 (r8436)
Note: recreating "configure" with autoconf 2.61 does not work as is,
since the scripts require 2.59. To allow this, the two requirements
in "libffi/configure.ac" and "config/override.m4" were temporarily
changed.
========== libffi_msvc directory =====================================
This directory is synced from the CTypes repository
http://svn.python.org/projects/ctypes/trunk/ctypes
revision 60274.
