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

* 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.

   - 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
+    $(FCFLAGS_f[09]x) computed by AC_FC_SRCEXT is now used in compile rules.
 
   - Files with extension .sx are also treated as preprocessed assembler.
