Make should do the comparison automatically.  The trick is 
in the proper setup of the rules to perform the conversion.
Something like the following:

#######################################
# process the html pages into man pages
%.man: %.html
	html2man $< > $@

# make sure the man directory exists
$(GRASS_MANDIR):
	test -d $(GRASS_MANDIR) || mkdir -p $(GRASS_MANDIR)

# copy the man pages
$(GRASS_MANDIR)/%:% $(GRASS_MANDIR)
	cp $< $@
#######################################

The trick is in specifying the dependency of the man page
on the html page, and not just blindly executing the 
html2man process.
