:ADDPATCH fortran:

Hi all,

first, I'd like to wish a belate happy new year.

Secondly, gfortran currently fails to INCLUDE files specified by the
full path, e.g.

   include '/home/allan/slot2usl/physcons.inc'

The logic in gcc/fortran/scanner.c's open_included_file is:

  for include_path in include_paths
     try-to-open( include_path + filename )

The fix is simple: Try first to open the file without prefixing an
include path.

The following patch was tested on x86_64-unknown-linux-gnu; I also did
bootstrap and regression test it; furthermore, the patch was
pre-approved by Steven Bosscher (see PR30276). I don't see how one could
create a regression test for this ;-)

Ok for the trunk and after a week for 4.2?
