I have just updated the mingw-w64 cross compilers Cygwin 32bit and
64bit to mingw64-{i686,x86_64}-gcc-5.4.0-3.

This version uses POSIX threads to support C++11 std::thread, as a
consequence, require winpthreads.

Unlike the Cygwin gcc, this version DOES NOT PRESERVER C++ ABI from
gcc4. Please rebuild all your C++ libraries.

==== PLEASE RECOMPILE ALL YOUR C++ CODE FOR ABI COMPATIBILITY ====

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.

Hi Jon,

What will be left as prev? 5.4.0-2, or the last 4.9 build? Can you
help raise https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77333? The
interprocedural analysis that was added for gcc 5 is deeply buggy on
mingw targets, resulting in miscompiling C++ libraries like LLVM.
This is keeping me on gcc 4 indefinitely until it gets fixed. I may
have to abandon gcc and switch to clang due to this, but there are
many libraries that have broken build systems that behave incorrectly
when you try to use clang on Windows.

I'll use time machine if that's my only way to keep getting gcc 4,
but this bug in gcc should really be fixed or it's going to start
showing up in cygwin-mingw-cross and msys2 packages.

Thanks,
Tony

Jon,

Can you make 4.9 the previous version? Thanks.

Sorry, the files for 4.9.3-1 are no longer on sourceware.

I guess they got removed when you uploaded 5.3.0-3 (28/02/16)

Sorry, I guess you'll have to rebuild as gcc-4.9.3-2 and upload that, if 
this is really needed.
