This broke the compilation with gcc 2.95:

<--  snip  -->

...
  gcc -Wp,-MD,fs/jfs/.super.o.d -D__KERNEL__ -Iinclude -Wall
-Wstrict-prototypes -Wno-trigraphs -O2 -fno-strict-aliasing -fno-common
-pipe -mpreferred-stack-boundary=2 -march=k6

fs/jfs/super.c: In function `jfs_fill_super':
fs/jfs/super.c:335: parse error before `)'
make[2]: *** [fs/jfs/super.o] Error 1

Curious as to what gcc 2.95 version you are using.
Seems to compile fine with:
gcc 2.95.4 20011002

I'm using the same gcc. I should have said that I'm compiling with
CONFIG_JFS_DEBUG. Without CONFIG_JFS_DEBUG it indeed compiles fine.

1. JFS no longer compiles with gcc 2.95

I'm not sure what's causing the problem, but Andrew Morton send me this
patch which gets rid of the problem for him.  The fmt string that
jfs_err() is invoked with is sufficient to identify the location, so
__FILE__ and __LINE__ are not really needed anyway.

Linus, please apply.

Thanks,
Shaggy
