glibc-2.2.5 fails to build using m68k-linux gcc-3.1.1-20020719

[Peter Barada]

I grabbed gcc-core-3.1.1-20020719 and tried to build glibc-2.2.5
targetting for m68k-linux (see
http://gcc.gnu.org/ml/gcc/2002-07/msg01029.html for details) and it
blows up now trying to build stdio-common/errlist.c with:


m68k-linux-gcc ../sysdeps/unix/sysv/linux/errlist.c -c -O2 -Wall -Winline 
-Wstrict-prototypes -Wwrite-strings -g   -fpic    -I../include -I.

../sysdeps/unix/sysv/linux/errlist.c:41: weak declaration of `_old_sys_nerr' 
must precede definition
make[2]: *** 
[/home/pbarada/work/cvs-wavemark/cross-linux-tools/obj/crap/m68k-linux/glibc/stdio-common/errlist.os]
 Error 1

I've isolated it down to the follwing three lines from
sysdeps/unix/sysv/linux/errlist.c, line 26

>const int __old_sys_nerr = OLD_ERRLIST_SIZE;
>
>strong_alias (__old_sys_nerr, _old_sys_nerr);
>weak_alias (__old_sys_nerr, _old_sys_nerr)

Which expand into:

const int __old_sys_nerr = 123;

extern __typeof (__old_sys_nerr) _old_sys_nerr __attribute__ ((alias 
("__old_sys_nerr")));;
extern __typeof (__old_sys_nerr) _old_sys_nerr __attribute__ ((weak, alias 
("__old_sys_nerr")));

If I reverse the last two lines, it compiles without complaint.
