I have some vague memory about reading that the semantics of 'inline'
has changed recently.  If you don't mark inline functions static, they
will be exported as well, because they may be needed in other files.
That would explain this problem.  I may be remembering incorrectly, but
it may be that this new behaviour is actually correct.

I can't find this symbol in the GnuTLS sources, so I would suspect it is
used in Guile?

This reminds me, there is a bunch of warnings about use of inline
functions in the gnutls-guile code, such as:

core.c:1335: warning: function ‘set_certificate_file’ can never be inlined because it uses alloca (override using the always_inline attribute)
core.c:1335: warning: inlining failed in call to ‘set_certificate_file’: function not inlinable

I don't think this is related, though.
