[PATCH] Add new Fortran vector math header file.

["Martin Liška" <mliska@suse.cz>]

[-- Attachment #1: Type: text/plain, Size: 561 bytes --]

Hi.

The patch adds support for Fortran vector math routines as added
into GCC 9.  The header files will be installed to the same
folder as math-vector.h.

Thanks,
Martin

ChangeLog:

2019-02-18  Martin Liska  <mliska@suse.cz>
