The advantage of putting into GCC is that it will work irrespective of the installed glibc header version, so if we get this going: <https://sourceware.org/ml/libc-alpha/2018-05/msg00501.html> you could use libmvec along with really old glibcs (probably as far back as 2.12, maybe even older). But then we might into a different direction altogether. Another question is wheter the Fortran header can be generated by something like -fdump-ada-spec, so that we don't have to maintain it separately from the C header.
