I am using icpc (non optional) and I am compiling with -std=c++0x so I can use lambas.
However when I do so it creates havok with gcc stdlib with features that one supports that the other doesn't.
I have tried defining
__GXX_EXPERIMENTAL_CXX0X__
but that didn't help.
So ideally what I am asking for is the ability to use the c++0x language features with the C++03 stdlib.
gcc 4.6
icc 12.1]
EDIT example of error:
/usr/include/c++/4.6.2/type_traits(74): error: identifier "constexpr" is undefined

The errors obviously point to C++11 code, so it sounds like you want to prevent the compiler from seeing any of that, such as with -U__GXX_EXPERIMENTAL_CXX0X__ (the equivalent GCC option).
However, if ICC is defining this for you under -std=c++0x, then you should find out what version of the library you are supposed to use (or look for a library in your local ICC installation). It's far from certain that the C++03 library is sufficient to compile C++11 code.
icpc only warns at such situation. Do not put attention on this. Everything will be compiled.
