Yes, these annotations are correct.  You don't have to put them on a
line by themselves, though,

+! Platform-specific Fortran SIMD declarations of math functions. -*- f90 -*-

would also work.  As long as I'm looking at this patch, I have two
editorial notes:

In both new files, "Platform-specific Fortran SIMD declarations of
math functions" would be clearer with different word order: suggest
"Platform-specific declarations of SIMD math functions for Fortran."

In the generic file, "Get default empty builtin definitiones." has a
typo ("definitiones" should be "definitions"), and having a sentence
starting with "Get" on the last line of the file makes it look like
there's something missing.  Suggest instead "No SIMD math functions
are available for this platform."
