[Patch, Fortran] PR40569/40568: Support intrinsic module procedures (F2008)
- From: Tobias Burnus <burnus at net-b dot de>

- Subject: [Patch, Fortran] PR40569/40568: Support intrinsic module procedures (F2008)
This patch add support for compiler_version and compiler_options,
which are part of F2008's ISO_FORTRAN_ENV. It also moves c_sizeof into
the module ISO_C_BINDINGS where it belongs to (before it was a normal
intrinsic).
TODO:
a) With -Wall I get the warning that the intrinsic is already typed.
b) compiler_options returns an empty string.
I plan to look into those issues as once as the patch is in.
Build and currently regtesting on x86-64-linux.
OK for the trunk?
Tobias
