[PATCH] Add support for newer Fortran extensions '.[fF]0[38]'.

[Ralf Wildenhues]

* automake.in (scan_autoconf_traces): Accept .f03, .f08 for
Fortran, .F03 and .F08 for preprocessed Fortran files.
Use $(FCFLAGS_f[09]x) accordingly.
* doc/automake.texi (Compiling Fortran 9x Files): Update.
* tests/fort2.test: Add more tests.
* NEWS: Update.
---

I noticed that GCC now also supports the .f08 extension (and that I had
missed the addition of support for .f03).  Applied to master.

Cheers,
Ralf

   - subdir-object mode works now with Fortran (F77, FC, preprocessed
     Fortran, and Ratfor).
 
-  - For files with extension .f90 or .f95, the flag $(FCFLAGS_f9x)
-    computed by AC_FC_SRCEXT is now honored in compile rules.
+  - For files with extension .f90, .f95, .f03, or .f08, the flag

   - Files with extension .sx are also treated as preprocessed assembler.
