Also handle __STDC_WANT_IEC_60559_BFP_EXT__ in <tgmath.h>.
My __STDC_WANT_IEC_60559_BFP_EXT__ patch omitted to update the conditions on the nextup and nextdown type-generic macros in <tgmath.h>. This patch updates those conditions accordingly. (As glibc doesn't currently have an exp10 type-generic macro, no such changes are needed relating to __STDC_WANT_IEC_60559_FUNCS_EXT__; adding such a type-generic macro would be a new feature.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). Committed. * math/tgmath.h (nextdown): Define if [__GLIBC_USE (IEC_60559_BFP_EXT)], not if [__USE_GNU]. (nextup): Likewise.
