But not a valid use of gmpxx. You can compare to other packages. For
instance, freetype or gtk typically require -I/usr/include/freetype2 or
-I/usr/include/gtk-2.0. These packages have many header files that include
each other, but still use the <> notation. I don't see why gmp should be

I don't like it (but I don't decide). However, having a test in gmpxx that
checks whether the version of gmp.h included matches and outputs a warning
(not an error, there can always be good reasons to do strange things)
otherwise would help diagnose this kind of issue.
