As far as I can tell these are neither part of the Standard Predefined
Macros nor of the Common Predefined Macros, so these can only be part
of the System-Specific Predefined Macros.

And the C standard requires that all System-Specific Macros be part
of the _reserved_namespace_ (i. e. the names must begin with two
underscores, or an underscore and a capital letter).

So if a C compiler auto-defines something as "arm", or "i386", or
"microblaze", then it is NOT standard-conforming - bare with me if I
simply call this broken.

Best regards,

Wolfgang Denk
