GMP is covered by LGPL, so must any such derivative work

But the wrapper is just using GMP as a library, so it shouldn't be infected with LGPLness, should it? If a lawyer for the PSF can confidently assert that gmpy is not a derivative work of GMP, I'll have no problem changing gmpy's licensing. But I won't make such a call myself: for example, gmpy.c #include's gmp.h and uses (==expands) some of the C macros there defined -- doesn't that make gmpy.o a derived work of gmp.h? I'm quite confident that the concept of "derived work" would not apply if gmpy.so only accessed a gmp.so (or other kinds of dynamic libraries), but I fear the connection is stronger than that, so, prudently, I'm assuming the "derived work" status until further notice.

Well we already wrap readline, would this really be any worse?
Readline is GPL.
