First I wrote the patch to cpu.c and posted it here:
Then I posted a second version of this patch (so the patch above is obsolete):
This second version was split into two files:
* the first part contains fixes ( CALLBACK -> WINAPI, updated URLs in comments,
"r"(sse) -> "0"(sse), etc)
* and the second part contains a code for SSE support detection when a compiler
is MinGW/GCC and target OS is Win32.
The latest change in configure.ac makes this second part mostly useless
because by default it will be thrown away by preprocessor.
So, about the patches from http://lists.xiph.org/pipermail/flac-dev/2014-March/004577.html
* The patch cpu_part1.patch should be applied;
* The patch cpu_part2.patch (already applied) is almost useless now, so why keep it?
It can be useful only for those who want to use MinGW/GCC to compile Win95-compatible
libFLAC.dll or Win95/WinNT4 compatible flac.exe. Do these people exist?
