Hello John,

sure the Makefile fragment in:

gcc/gm2/Make-lang.in:2130

gm2/ppg$(exeext): gm2/boot-bin/mc $(BUILD-PPG-O) $(BUILD-MC-INTERFACE-O) 
gm2/gm2-ppg-boot/main.o
        $(CC) -g -o $@ $(BUILD-PPG-O) gm2/gm2-ppg-boot/main.o -lm -lpth

with the $(CC) recipe

and also at

gcc/gm2/Make-lang.in:2174 for pg

gm2/pg$(exeext): gm2/boot-bin/mc \
    $(BUILD-PG-O) $(GM2-PPG-MODS:%.mod=gm2/gm2-pg-boot/%.o) \
    $(BUILD-MC-INTERFACE-O) gm2/gm2-pg-boot/main.o
        $(CC) -g -o $@ $(BUILD-PG-O) gm2/gm2-pg-boot/main.o -lm -lpth

and

gcc/gm2/Make-lang.in:2237

gm2/pge$(exeext): gm2/boot-bin/mc \
    $(BUILD-PGE-O) $(GM2-PPG-MODS:%.mod=gm2/gm2-pge-boot/%.o) \
    $(BUILD-MC-INTERFACE-O) gm2/gm2-pge-boot/main.o
        $(CC) -g -o $@ $(BUILD-PGE-O) gm2/gm2-pge-boot/main.o -lm -lpth
        $(srcdir)/gm2/tools-src/buildpg $(srcdir)/gm2/gm2-compiler/ppg.mod t > 
gm2/gm2-auto/t.bnf
        ./gm2/pge$(exeext) gm2/gm2-auto/t.bnf > gm2/gm2-auto/t1.mod
        ./gm2/pg$(exeext) gm2/gm2-auto/t.bnf > gm2/gm2-auto/t2.mod
        $(QUIAT)if ! diff gm2/gm2-auto/t1.mod gm2/gm2-auto/t2.mod > /dev/null ; 
then \
           echo "failure: pg (with error recovery) failed" ; \
           $(RM) gm2/pge$(exeext) ; \
           exit 1 ; \
        fi
        $(RM) gm2/gm2-auto/t.mod gm2/gm2-auto/t1.mod gm2/gm2-auto/t2.mod

hope that helps,
