Linux biloute 3.2.29-smp #2 SMP Mon Sep 17 13:16:43 CDT 2012 i686 Intel(R) Core(TM)2 Duo CPU    T5450  @ 1.66GHz GenuineIntel GNU/Linux

... Fedora core 3 is based on the "Linux 2.6.x" kernel series, and those have all been written to compile with the "Fedora Core 3" compiler, which is gcc version 3.x.

I see that the kernel you are trying to compile is a "Linux 2.4.x" kernel, which is written to compile with the older/obsolete gcc 2.x compiler. the "2.4" kernel and the "2.x" gcc compiler are both standard "Fedora Core 2" packages, but you are currently running "Fedora Core 3"....

First, save your current kernel configuration file, "/usr/src/yourlinuxversionhere/.config" by copying it someplace safe:

"cp /usr/src/yourlinuxversionhere/.config /root/config.save"

Then clean up your current "build attempt" with:
"make mrproper" (note: this will delete the ".config" file in the directory "/usr/src/yourlinuxversionhere", so I hope you made the backup copy noted above.).

Now, then, no promises because I haven't tried this yet.

"cp /root/config.save /usr/src/yourlinuxversionhere/.config " (this will give you the old config file back)
"make oldconfig" (this is the part that I am not certain will work, if it doesn't , no harm done, if it does you might be in luck)

Then try the "make ; make install"

Code:

  echo "#"
  pwd
  echo `pwd`/$DEFAULTS
  ls -a
  . `pwd`/$DEFAULTS
  sed -e 's/# \(CONFIG_[^ ]*\) is not.*/\1=n/' <$DEFAULTS >.config-is-not.$$
  . `pwd`/.config-is-not.$$
  rm `pwd`/.config-is-not.$$
else
  echo "#"
  echo "# No defaults found"
  echo "#"
fi

Googling on this I found:

Since I used the --prefix for gcc compilation, I figured the problem may be the one specified in :-
http://gcc.gnu.org/faq.html
and in particular, "How to install multiple versions of GCC". This also says the solution would be:-
