I don't see why that should be needed, as long as the library simply
doesn't build for x86 and doesn't cause build failures, cause
__STDC_DEC_FP__ to be defined on x86, etc. - I'd expect it to be built by
default for supported architectures (Power and S/390), given that the
compiler is recent enough to have DFP support for those architectures, and
not at all for others - x86 should be considered much like ARM (an
architecture with no DFP support in GCC) in this regard. (Ideally,
defining __STDC_WANT_DEC_FP__ would cause an error on unsupported
architectures.)
