Linux 1.2.9 compilation problem with gcc-2.7.0

I compiled gcc-2.7.0 for linux-aout (haven't converted to ELF yet) and
went to recompile Linux-1.2.9.

Here's what happened when I tried to ``make modules'':

gcc -D__KERNEL__ -I/usr/src/linux/include -Wall -Wstrict-prototypes -O2 -fomit-frame-pointer -pipe -m486 -DMODULE -DCONFIG_MODVERSIONS -g -c 53c7,8xx.c

It appears that gcc-2.7.0 no longer allows preprocessor directives to
be recognized inside macro invocations.

The following trivial patch fixes the kernel source:
