[Bug c++/56038] declarations in xmmintrin.h conflict with mingw-w64 intrin.h in c++ mode
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56038 --- Comment #12 from Erik van Pienbroek erik-gcc-bugzilla at vanpienbroek dot nl --- (In reply to tim.lebedkov from comment #11) Qt 5.2.1 cannot be build in 32 bit with mingw-w64 4.8.2 because of this bug. Why is it not fixed? A fix for this issue was applied in the intrin.h of mingw-w64 v3.1.0 (which was released in January 2014). Here's the commit in question: http://sourceforge.net/p/mingw-w64/code/6303/ You might want to consider updating your toolchain. I can't judge whether the fix applied in mingw-w64 is correct or whether something needs to be changed in gcc itself as well. Therefore I'm leaving this bug open for now. If the gcc devs think otherwise feel free to close this bug. Qt5 itself can now be built properly against gcc 4.8.2 and mingw-w64 v3.1.0 without any issues.

Bug #: 56038
Summary: declarations in xmmintrin.h conflict with mingw-w64
intrin.h in c++ mode
Classification: Unclassified
Product: gcc
Version: 4.8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
AssignedTo: unassig...@gcc.gnu.org

Target: i686-w64-mingw32
Build: gcc 4.8 20130106 snapshot, r194954
While testing gcc 4.8 (for the target i686-w64-mingw32) I stumbled across a
compile failure while trying to build Qt5. Here's a minimal testcase to
reproduce this compile failure:
#include algorithm
#include intrin.h
int main()
{
return 0;
}
When trying to build this with gcc 4.8 and a recent mingw-w64 trunk snapshot
the following error occurs:
$ i686-w64-mingw32-g++ -O2 -msse2 -std=c++11 test.cpp

The above testcase built fine with gcc 4.7 and the exact same version of
mingw-w64, so I consider this a regression in gcc 4.8
With the (pretty straightforward) change below I managed to resolve the issue:
