Weird. I've certainly tried it with intel 11.1 and it worked without a
problem. I guess we'll have to add a configure check for this and,
like Julian suggested, use size_t if uintptr_t isn't available.

Yes, unless --disable-cxx-flags-preset is used. This has been the case
since as long as I remember, but whether it's desired is more
questionable to me. It seems that even with the autodetected options,
the CXXFLAGS should be *added* to the compiler flags, not just
overridden, but I don't know why it works like it does.
