This update includes: Update: mingw64-*-headers-3.0b_svn5935-1 mingw64-*-runtime-3.0b_svn5935-1 mingw64-*-gcc-4.7.3-1 mingw64-*-pthreads-20100619-5 New: mingw64-*-winpthreads-3.0b_svn5935-1 *** NOTES *** For gcc-4.7.x, struct alignment behavior has changed, -mms-bitfields is now default, for better MSVC compatibility. This may cause ABI changes in libraries that expose data structures directly to clients. Workaround include marking the struct with the gcc_struct attributes. The pthreads package is now a stub containing only runtime DLL, the POSIX threads headers and link libraries are now provided by the winpthreads package. The mingw64-*-headers package now has winpthreads as a prerequisite as well, some of the headers from the headers package are overwritten on purpose by the winpthreads package. ****** The cross compiler can produce Win32 and Win64 native binaries. As a cross compiler, you may use --host=i686-w64-mingw32 or --host=x86_64-w64-mingw32 for autotools based source packages to build for Windows. *** CYGWIN-ANNOUNCE UNSUBSCRIBE INFO *** If you want to unsubscribe from the cygwin-announce mailing list, look at the "List-Unsubscribe: " tag in the email header of this message.
