I'm using the following for loop in a makefile that works fine with both pmake
and gmake:

SUBDIRS = lib scripts support

all clean cleanclean install:
        @for dir in $(SUBDIRS) ;\
        do \
                (cd $$dir ; echo "making $@ in $(CURRENT_DIR)/$$dir..." ;
$(MAKE) $(MFLAGS) $@ ) ;\
        done

Hopefully that'll help.  The only thing is that you need a semicolon before the
do and after every statement.  Also, it wants a for loop to all be on one line
(?) so that you have to use \'s to make it concatenate the various lines.  The
ampersand on the for is to prevent the command from being echoed, btw.
