But why would you declare alloca() as a function even though you're not going
to use it (as far as I understand you don't use it if HAVE_ALLOCA is not set)?!

I don't think this is correct, as alloca() may be available even
though HAVE_ALLOCA is not defined (e.g. with MinGW).

Hi,
GMP-6.1.2 fails to compile with CompCert (compcert.inria.fr) on Linux x86-64.
The reason is that one of the header files in GMP declares alloca() with a
prototype that conflicts with the one in the system headers.
Steps to reproduce:
$ CC=/opt/CompCert/3.4/x86_64-linux/bin/ccomp
