Trying to build an Installation Kernel from sources sup'ed yesterday and I'm
getting this error:

cc  -O2 -Werror -Wall -Wstrict-prototypes -Wmissing-prototypes  -Wpointer-arith -Wno-main -msoft-float -I. -I../../../../arch -I../../../.. -nostdinc -I../../../../../gnu/sys -DHZ="0x3c" -DM68040 -DM68030 -DM68020 -DFPSP -DFPU_EMULATE -DDIAGNOSTIC -DMAXUSERS=8 -D_KERNEL -Dmac68k  -c ../../../../arch/mac68k/dev/if_mc.c

../../../../arch/mac68k/dev/if_mc.c: In function `mace_read':
../../../../arch/mac68k/dev/if_mc.c:672: warning: unused variable `eh'
*** Error code 1

Looking at the source line it's a comment, which doesn't make any sense. Also
the build of a non-installation kernel on these same sources worked fine.

Any clues?
