sorry. Here's a new patch that applies cleanly against the latest version of that macro, using 'patch -p0'.

I am sorry, but the patch does not apply to the latest version of the macro (#serial 12) from <http://www.gnu.org/software/autoconf-archive/ax_ext.html>. Could you please check that you've used the latest version of the file to generate that patch?

On platforms where
AX_GCC_X86_CPUID(0x00000001)
returns 'unknown', the AX_EXT macro would currently break configure with an error:

[eg see https://pm.bsc.es/projects/mcxx/ticket/1201]
checking for x86 cpuid  output... unknown
checking for x86 cpuid 0x00000001 output... unknown
checking whether mmx is supported... ../mcxx/configure: 0xunknown: value too great for base (error token is "0xunknown")

The fix is trivial, simply handle the special return value 'unknown' properly.

The attached patch implements this [taken from
https://pm.bsc.es/projects/mcxx/ticket/1201
https://pm.bsc.es/projects/mcxx/changeset/12fd7dc2ac9336fdd296e117165daba4bb2dcdac]

I have verified that this patch fixes the problem.
