Linux build failed : __SSE__ not declared and __declspec

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to build on linux

I get this:
/usr/lib/gcc/i686-pc-linux-gnu/4.7.2/include/xmmintrin.h:32:3: error: #error 
"SSE instruction set not enabled"

If I manually add SSE flags I reach another problem:
/src/nvmath/Half.cpp:500:5: error: ISO C++ forbids declaration of 
‘__declspec’ with no type [-fpermissive]

So it seems that __declspec is used on Linux.

gcc version 4.7.2 (GCC)
nvtt svn r1357

I think it's a problem in CMAKE_CXX_FLAGS variable coming from 
OptimalOptions.cmake. (fix_cxx_flags.patch).

In this part of code it's forgotten about gcc (fix_declspec.patch).

gcc version: gcc (SUSE Linux) 4.7.1 20120723 [gcc-4_7-branch revision 189773]
