Matthew Flatt 03259ef539 MinGW-w64 support For now, SGC must be used, but `configure' does not select it automatically. Also, support Cygwin (in addition to MSYS) as a build environment when using MinGW compilers. Since I build in a Cygwin environment (which seemed to be the easiest way to get MinGW-w64 gcc), I use ../configure --host=x86_64-w64-mingw32 --enable-sgc		2012-12-28 11:06:46 -06:00

========== libffi directory =============================================

Our copy of libffi for Racket has been changed in a few small
ways at git commit 3f5b1375ab1e2b8e3d59 from

 http://github.com/atgreen/libffi

Local changes:

 * Test ftruncate() result in "closures.c" to avoid a compiler
   warning.

 * Added powerpc .S patches from 2d3fb36420e09304220e

 * In "darwin.S", added ".long 0" after ".LFE3:" to avoid
   linker problems compiling with gcc-4.0 on Mac OS X 10.7.

========== libffi_msvc directory =====================================

This directory is synced from the CTypes repository
