Bootstrapping with Fortran enabled fails for 4.0.1 if "-pipe" is included
among flags passed through to library builds. It used to work for 4.0.0.
The reason is "libgfortran/intrinsics/f2c_specifics.F90", which is new to
4.0.1, and the "%|" operator used in the specs
("gcc/fortran/lang-specs.h") which does not expect numeric characters:
/home/macro/src/redhat/BUILD/gcc-4.0.1/obj/gcc/gfortran
-B/home/macro/src/redhat/BUILD/gcc-4.0.1/obj/gcc/ -B/usr/i386-linux/bin/
-B/usr/i386-linux/lib/ -isystem /usr/i386-linux/include -isystem
/usr/i386-linux/sys-include -DHAVE_CONFIG_H -I. -I../../../libgfortran -I.
-iquote../../../libgfortran/io -Wall -fno-repack-arrays -fno-underscoring
-pipe -O2 -fomit-frame-pointer -mtune=i486 -c
../../../libgfortran/intrinsics/f2c_specifics.F90 -fPIC -o
.libs/f2c_specifics.o
cc1: warning: command line option "-fno-repack-arrays" is valid for F95
but not for C
cc1: warning: command line option "-fno-underscoring" is valid for F95
but not for C
f951: error: unrecognized command line option "-95"
The following patch fixes the problem for me -- digits should be safe to
accept in file names, shouldn't they?

* gcc.c (do_spec_1): Accept numeric characters in file name
suffixes.
Tested successfully in a native bootstrap for "i386-linux-gnu" for GCC
4.0.1. Inspection of sources shows it is needed for HEAD as well.
