Yes, this is a very annoying problem that I reported to Intel some time ago,
but they seem to have done nothing about it. Another solution beside the
one that Patrick has suggested would be to add the flag -cxxlib-icc to
request use of the Intel headers and C++ runtime libraries rather than the
gcc ones. For some reason, they have made gcc compatibility with the
-cxxlib-gcc the default behaviour, even though their compiler cannot handle
header files from gcc 3.3 or later. I think if you add -cxxlib-icc to
-strict_ansi, it will work properly. You might consider adding the
-cxxlib-icc flag to your icpc.cfg file to make this a default flag for your
Intel C++ compiler installation.
