Michael Filonenko 35a093469c windows: extflonum support Enable extflonums in a MSVC build by relying on a MinGW-built DLL, "longdouble.dll". The DLL is loaded on startup. If the DLL isn't available, then `extflonum-available?' reports #f. Instead of setting the floating-point mode globally to extended precision, the mode is changed only just before (and restored right after) extflonum arithmetic operations.		2013-03-18 07:42:32 -07:00

========== 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

  http://svn.python.org/projects/ctypes/trunk/ctypes

revision 60274.
