They're not part of ISO C; they are part of *the long double API provided
by glibc* (and thus need to be provided for any alternative long double
format just like any other semi-obsolescent but still-available long
double interface, e.g. qecvt).
Is it possible to provide these particular functions in the API without
adding extra ABIs for them? For example, if the relevant case in math.h
had #defines of __dremieee128 or __ieee128_dreml or whatever it ends up
being to the corresponding name for remainder, and likewise for gamma /
lgamma, would that work correctly with __REDIRECT to get calls to dreml
and gammal working for -mabi=ieeelongdouble without needing to add two new
ABIs and two new source files?
