preprocessor symbol to distinguish s390, s390x?

[Steve M. Robbins]

Hi,

I just uploaded a fixed version of gmp that builds on s390x.
However, I realized that both s390 and s390x use the
same include file, gmp-s390.h.

In order to avoid this clash (see /usr/include/gmp.h), I need a C
preprocessor symbol that s390x defines but s390 does not. Perhaps
__s390x__ ?

Thanks,
-Steve

yep. __s390__ is defined on both of them, __s390x__ is only defined on s390x.
