SubjectCompile issue with test8 and gcc 2.95.2
Actually, I've been having a problem compiling the kernel ever since test7
(test6 compiled fine for me). The errors I see include both segfaults
(which I thought might be memory related, but alas no), and the
folling "parse" error:

----------------------------------------------------------------------

----------------------------------------------------------------------

Another parse error happens when I try to continue on by re-exec'ing
'make bzImage'...

----------------------------------------------------------------------

They don't seem related, but I could find no hidden characters in the
header files and could find no syntax errors at first and second
glance.

I downloaded linux-2.4.0-test8.tar.gz and ..tar.gz.sign earlier this
morning and verified the tarball with the signature (success).

I'm a bit baffled. I've rarely had problems compiling a kernel, but
this is one I can't get past. I'm using Debian's woody dist with gcc
2.95.2-14.

On a whim, before I sent this email off, I tried to compile the kernel w/o optimization (I deleted -O2 from Makefile). This is the error I ran in to:

----------------------------------------------------------------------
gcc -D__KERNEL__ -I/usr/src/linux-2.4.0-test8/include -g -Wall -Wstrict-prototypes -fomit-frame-pointer -pipe -mpreferred-stack-boundary=2 -march=k6 -fno-strict-aliasing -fno-omit-frame-pointer -c -o sched.o sched.c
sched.c: In function `schedule':
sched.c:649: Invalid `asm' statement:
sched.c:649: fixed or forbidden register 6 (bp) was spilled for class GENERAL_REGS.
make[2]: *** [sched.o] Error 1
make[2]: Leaving directory `/usr/src/linux-2.4.0-test8/kernel'
make[1]: *** [first_rule] Error 2
make[1]: Leaving directory `/usr/src/linux-2.4.0-test8/kernel'
make: *** [_dir_kernel] Error 2
----------------------------------------------------------------------

Might this have something to do with it?
