i386-linux build failure

   host: i386-linux
version: cvs update 11/6/98 morning

It seems the makefile is now attempting to run gperf with a mysterious
"-F" option for which I can find no documentation:

Making all in makeinfo
make[3]: Nothing to be done for `all'.
make[1]: Nothing to be done for `all'.
gperf -L KR-C -F ', 0, 0' -p -j1 -i 1 -g -o -t -G -N is_reserved_word \
   -k1,3,$ ./c-parse.gperf >tmp-gperf.h

Try `gperf --help' for more information.

I've upgraded to gperf-2.7, but it still doesn't support -F afaict. Does 
anyone know the purpose of the -F option?
