Hi,

can you please post more details about your build environment?
E.g., the output of
cc -v
cc -dM -E - < /dev/null

The latter should output all preprocessor defines, excluding/including
the culprit 64b macros.

According the best source I am aware of
(https://sourceforge.net/p/predef/wiki/Architectures/) both, __amd64__
and __x86_64__ should be equivalently available in all systems we care
about. But as Nico stated we have used both (and some additional
variations) in various places which makes such breakage possible.
Maybe we should use a similar approach as for discerning OSes with a
central header file defining our own macros... I have once started such
a thing in hwaccess.c.
