Wouldn't other C programs have the same problem anyway?
And such programs can't use something like that:

So, I wonder if gmp shouldn't use something like pkg-config
(though its design is somewhat buggy). At least, adding
`pkg-config --cflags gmp` to CFLAGS when the first try to
compile and link with GMP fails wouldn't hurt.
