I don't know, CCing Florian; all I can see is that starting with glibc 2.26
in addition to sin{f,,l} there is also sinf128, but dunno if glibc headers
transparently map sinl to sinf128 or something else for the IEEE quad long
double or what. But I believe glibc is like libstdc++ in that the same
libc.so.6 is ABI compatible with both ABIs (well, also the one where
long double is double, in that case I think glibc headers transparently
remap sinl to sin etc.).
