While that would certainly work in theory, I don't think this is a very
practical trick: you'd have to rewrite a huge amount of code (the standard
library is big !), and the result would really only be useful to catch
the kind of 'bugs' you are talking about. You wouldn't be able to actually
do much with the code (such as compile it), as each compiler does in fact
have its own version of standard (and not so standard) headers.
