Worse, passing -I/usr/include causes problems with some versions of GCC
on some platforms as GCC generates "fixed" versions of vendor supplied
include headers at build time.  Normally these are used instead of those
in /usr/include, but if you explicitly pass /usr/include you get the
non-fixed versions.  The most recent GCC versions ignore "-I/usr/include"
in this situation.

So that's why xapian-config carefully excludes -I/usr/include from
--cxxflags.

I'll put the above explanation as a comment in the script...
