problem building glibc-2.3.2 with gcc-3.4.0 and binutils-2.15.90.0.3 for m68k

[Dan Kegel]

While testing all the targets crosstool supports with the new combination of tools
(gcc-3.4.0 and binutils-2.15.90.0.3),
I ran into an error with --host=x86-linux --target m68k-linux:

localealias.s:544: Error: junk at end of line, first unrecognized character is `,'

Here are lines 544 to 546 of localealias.s:
     544         .local  lock
     545         .comm   lock,24,2
     546         .section        __libc_freeres_ptrs
So I guess it didn't like the ,24,2 on the .comm line.

Since I changed both gcc and binutils versions at once,
I have no idea which of the two changes triggered the problem.

This reminds me a bit of the problem I had compiling
that combination for --host=x86-cygwin --target=x86-linux,
maybe some configury bit is screwed up somewhere in gcc-3.4.0.

I'll leave demo-m68k.sh at gcc-3.3.3 for the moment.  One of
these days I'll try to track this down, maybe.

This assembler syntax is fairly common, and has been supported for a 
long time.  It works fine if I build a cross assembler to m68k-linux 
from current FSF development sources.

Perhaps gas was miscompiled.  It is also possible gas was misconfigured, 
but if so this would have to be pretty a pretty obvious error which 
should be easy to spot.

The flow in gas should be obj_elf_common, s_comm_internal, 
elf_common_parse, parse_align, and when parse_align returns, 
input_line_pointer should be pointing at the end of the input line (or 
perhaps pointing as whitespace).

No, gas is actually complaining about line 547 (it does not properly count
lines in #APP/#NO_APP sections).  See the thread starting at
<http://sources.redhat.com/ml/binutils/2004-04/msg00646.html>.

Thanks, Andreas!  I'll apply that patch to binutils-2.15.90.0.3 in the next release of crosstool.
