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

(file #30687)

I am sorry, but the patch does not apply to the latest version of the macro (#serial 12) from <>. Could you please check that you've used the latest version of the file to generate that patch?

On platforms where
returns 'unknown', the AX_EXT macro would currently break configure with an error:

[eg see]
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]

I have verified that this patch fixes the problem.
