Version:  pgcc -v
Reading specs from /usr/lib/gcc/i586-pc-linux-gnu/pgcc-2.91.66/specs
gcc version pgcc-2.91.66 19990314 (egcs-1.1.2 release)

(it's the binary that i downloaded straight off the PGCC web page (tgz
format, glibc2.x)

Error when compiling clean kernel 2.2.13 with following command:
time make bzImage

NOTE: I manually modified   /usr/src/linux/Makefile and
/usr/src/linux/arch/i386/Makefile  in order to change all -O2 to -O6
and added -mpentiumpro and -march=pentiumpro  
here's the output:

gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O6
-fomit-frame-pointer -mpentiumpro -march=pentiumpro -fno-strict-aliasing
-D__SMP__ -pipe -fno-strength-reduce -malign-loops=2 -malign-jumps=2
-malign-functions=2 -DCPU=686 -mpentiumpro -march=pentiumpro   -c -o

FURTHER NOTES:
this same kernel tree compiled just fine (with same optimization options)
but with pgcc 2.90.60 i think it was (pgcc-1.1.1-1) 

I wanted to try the newer one because I have been having crashes with any
kernel compiled with -mpentiumpro -march=pentiumpro  when trying to run
games such as Q3demoTEST and UnrealTournament  ( seems like the sound
locks up the games and they lockup the machine )

Hope this helps!
