gnutls guile warnings

[Simon Josefsson]

Hi Ludo,

building recent GnuTLS gives some warnings:

The cause seems simple: including "config.h" is not done as the first
thing in these files, so gnutls/compat.h ends up being included before
config.h.  The solution is to make sure "config.h" is included first.
However, I'm not sure how you would prefer to fix this, so would you
mind taking a look at this?  I can fix this later if you don't have
time, but then I'll do it my way which may not be what you want. :-)
