| I think this is your best bet if you don't want to have separate
| configurations, e.g.,
|
|
| driver_pg: dbfile_pg.o common.o
|
| driver_inf: dbfile_inf.o common.o
|
|
| %_inf.c: %.ec
|       infc ...
|
| %_pg.c: %.ec
|       pgc ...
|
|
| -boris
|

This isn't quite perfect because I need to maintain two rules of
essentially the same information, ie, the executable is made up of
dbfile.ec and common.c.  However, it is head and shoulders above what I
was trying to do because now I don't need to continually recompile and
reprocess the same files in case they were made for the other database.
~ Given there are relatively few programs compiled for both databases
it's a pretty good soloution.  For posterity, here's my rules:

# Makefile Include

# I have to copy here because the Informix precompiler
# does not allow you to redefine the output file
%_inf.ec: %.ec
~        cp $< $@


%_pg.ec: %.ec
~        cp $< $@


# Precompiler stage
%_inf.c: %_inf.ec
~        $(INFXEC) $<


%_pg.c: %_pg.ec
~        $(PGSQLEC) $<


# Make sure it is made with the correct include paths
%_inf.o: %_inf.c
~        $(CC) $(INCFLAGS) $(INFXFLAGS) -c -o $@ $^


%_pg.o: %_pg.c
~        $(CC) $(INCFLAGS) $(PGSQLFLAGS) -c -o $@ $^


# Make sure it's linked with the correct libraries
%_inf:
~        $(CC) -o $@ $^ $(LDLIBS) $(INFXLIBS) -lcrypt


%_pg:
~        $(CC) -o $@ $^ $(LDLIBS) $(PGSQLLIB)


# Makefile
tagUtil_pg:     tagUtil_dbase.o db_tag_pg.o


tagUtil_inf:    tagUtil_dbase.o db_tag_inf.o


        Thanks for your help, and any further tips are more than welcome.
