compiler option -mpreferred-stack-boundary=2 problems

When I try to make my Kernal the compiler barfs at a known option. Here's the nohup.out from "make xconfig" in directory /usr/src/linux:

rm -f include/asm
( cd include ; ln -sf asm-i386 asm)
make -C scripts kconfig.tk
make[1]: Entering directory `/usr/src/linux-2.2.13/scripts'
gcc -O6 -fomit-frame-pointer -fno-exceptions -fno-rtti -pipe -s -mpentium -mcpu=pentium -march=pentium -ffast-math -fexpensive-optimizations -malign-loops=2 -malign-jumps=2 -malign-functions=2 -mpreferred-stack-boundary=2 -c -o tkparse.o tkparse.c
cc1: Invalid option `preferred-stack-boundary=2'
make[1]: *** [tkparse.o] Error 1
make[1]: Leaving directory `/usr/src/linux-2.2.13/scripts'
make: *** [xconfig] Error 2

Help! GNU's manual for gcc says that this option is fine. What's wrong? Is there a variable that should be set?

Do 'gcc -v'.  The preferred-stack-option doesn't work with gcc < 2.95.  Your manual may not be the right one for the version of gcc you're using.

Yeah, I have version 2.91.66. But I got the makefile, libraries and compiler from the same CDROM. Why would they use a different version of the compiler to build my kernal than the one they included on the CD?

How do I fix this problem. Do I download the latest gcc package or edit the makefile and remove the option?

hello , try to edit the Makefile and remove the invalid option (backup your original Makefile first)

Whoever put together your distribution probably just made a booboo.  I'd get the latest gcc package and install it rather than futzing with the makefile - the preferred-stack-option might be important (or not - but a newer gcc is probably better anyway).

I tried to use the latest version of gcc but kpackage complained that there were "conflicts" during installation

does kpackage run rpm?  You could try running it from an xterm and do --force --nodeps, or at least see what rpm doesn't like about the package - maybe there's something else that needs to be installed first -

It turns out that hotbot had the correct idea after all. (Sorry hotbot!) http://mandrakeuser.org has a perl script that removes the "preferred-stack-boundary=2 option from the Makefiles.
