 Together with the configure.in, it provides a -mcpu option to gcc (though
 MacPorts seems to override this setting), going against the default
 target; MPN_PATH (see configure output) is also affected, and I don't know
 whether MacPorts does something about it. Such a configuration should be
 done at a higher level, e.g. at the system level (Apple has done some
 choice in the configuration of the gcc provided by Xcode) or, here, at the
 MacPorts level (there's no reason why ''only'' GMP would use a different
 target). Moreover the -force_cpusubtype_ALL option (that is used in the
 Portfile) is probably contradictory. Disabling GMP's CPU subtype detection
 is probably the best thing to do.

 This is a bit like the ABI chosen by GMP, which can be different from the
 default ABI (chosen by Apple and MacPorts). Concerning this problem (much
 more critical), the Portfiles already fixes it:
 {{{
 if {![variant_isset universal]} {
     configure.env   ABI=32
 }
 }}}
