Can't make with SMP off and Modules on

On a Redhat 6.1 installation, I have the 2.2.14 kernel. If I configure
it with SMP off and Modules on, I get the following errors.

gcc -D__KERNEL__ -I/u/usr/src/clunix/linux/include -Wall -Wstrict-prototypes -O2

===============================================================
This also happened on a "stock 2.2.12-20" kernel on a 6.1 system, but
when a friend tried it with 2.2.13 on a Suse 6.4(?) system, it built
fine for him. I can get it to compile if I turn either SMP on, or
Modules off. Unfortunately, Vmware complains if I try to run with SMP
on, on a uniprocessor machine. It also complains if I try to run with
modules turned off.

Has anyone else seen this build problem with the 2.2 kernel? Is there a
known solution?

  Thanks for any help,
     Larry
