If they're going to be linked together, that's a very bad
idea. Otherwise, you could probably do it with some Makefile hackery.

Why? Why

The code is closed under some legal agreements, so I cannot release it,
neither send gcc a bug-report.
For baseline comparison sake, could you give a compilation round under
icc (Intel's i386 copiler)... It (the icc) is somewhat more pedantic
than gcc and might flush

The possibility that gcc is somehow sensitive to the legal status of
the code in question does not have to be ruled out.
How this might happen

I've stumbled with the following problem regarding gcc. Assume for a
moment I compile many files, some are header files, some are interface
files, and some are the real program.
When compiling with -O1 optimization things work,
do setenv CC /usr/bin/kgcc
or export CC=kgcc on bash

Hi,
Alex is right, you have to change the kernel's Makefile so it will use
kgcc insted of gcc. Alex is also correct that the answer I gave
appears in the manual.

Hi all.
Having recently installed RH7 I tried to compile several things, such as
modem driver, new kernel and modules, in all cases compiler (gcc) reports of
a bunch of errors and exits.
Both modem driver and kernel (2.3.9) compile OK in Slackware 7 on gcc-2.92.
Now I use version 2.96 of gcc,
