[Qt-interest] Problem building Qt 4.7.3 with Intel compiler on Linux

[Alexander Neundorf]

Hi,

I was not able to build Qt 4.7.3 with the Intel compiler
icpc (ICC) 11.1 20091130 (and  gcc 4.3.2)
on openSUSE 11.1 (Linux darkstar 2.6.27.48-0.12-default #1 SMP
2010-09-20 11:03:26 -0400 x86_64 x86_64 x86_64 GNU/Linux)

I got the following linker errors:

__builtin_isnan() and __builtin_isfinite() come from cmath.h.
So although simple isnan() is called, it results in std::isnan() being
called.
With the attached patch I was able to link it successfully.
