It's pointless trying to build anything with gcc 4.7.0. It's a totally
useless version of the compiler.
:-) Birthday edition...
Having said that, the function in question is a GMP_EXTERN_INLINE
function defined in gmp-impl.h. Unfortunately, GMP_EXTERN_INLINE is
not defined in gmp-impl.h.
I'll move the definition into gmp-h.in where it is actually defined.
I've no idea why this worked everywhere else but not on this system.
It could still be a compiler bug of course.
I haven't looked at this at all, but I'd guess it's related to the
optimization level, i.e., there usually don't remain any references to
that function.
Btw, invalid options to 'configure' (e.g. '--enable-gmp-compat' or
'--enable-foo') are silently ignored, even with '-v'; probably just some
(newer) autotools "feature"...
I think we possibly do this deliberately as some options need to be
passed to yasm's configure.
The recursive 'configure' is already called with
'--disable-option-checking' (or what it is called).
If you can give me a list of all possible invalid options users will
type, I'll make sure they are excluded. (Just joking.)
No space left on device... :-/
But you should certainly test for '--enable-gmpcombat'.
