I tried this:
--snip---
#include<iostream>
int main(void)
{
cout << "Hello World";
exit(0);
}
---snip---
- gcc from -current didn't fails (and no errors).
- icc complains about:
---snip---
test.cpp:
"/usr/include/stdlib.h", line 57: error: invalid combination of type specifiers
typedef _BSD_WCHAR_T_ wchar_t;
^
"/usr/local/intel/compiler50/ia32/include/cwchar", line 16: error: the global scope has no "tm"
using ::mbstate_t; using ::size_t; using ::tm; using ::wint_t;
^
"/usr/local/intel/compiler50/ia32/include/cwchar", line 19: error: the global scope has no "btowc"
using ::btowc;
^
"/usr/local/intel/compiler50/ia32/include/cwchar", line 22: error: the global scope has no "mbrlen"
using ::mbrlen; using ::mbrtowc; using ::mbsrtowcs;
^
[and so on]
---snip---
I think this is because of our wchar implementation (mostly a stub if I
remember correctly), but I could be wrong on this.

If you have to patch some Intel headers, then you have to work on a
"make pre-patch" version of icc. Don't forget to apply patch-include by
hand before you make diffs.
Bye,
Alexander.
