Adding -I/usr/include is a real problem since it subverts the
compilers notion of where to find headers. Remember that Gcc has
fixed-up a lot of headers and those should be used instead of the
onces in /usr/include. It is strongly advised to _not_ use
-I<system-include-dir> in the Gcc documentation.
Gcc 3.4 will even go so far as to just ignore any -I<system-inc-dir>
to avoid these problems.
