I strongly disagree with your remark.

I don't understand why you want to say explicit "libXpm.a".  Any make
rule that mentions that explicitly is bound to fail at some point.

| 
|            /tmp/axiom49/obj/fedora5/lib/bsdsignal.o 
-L/tmp/axiom49/obj/fedora5/lib -lspad  -L/usr/X11R6/lib -lXpm  -lX11 -lm 
-L/tmp/axiom49/obj/fedora5/lib )

These symbols are defined in X11.  So I highly suspect an ordering
error of the library you specify.

| so I have:
|     linux:  -l/usr/X11R6/lib/libXpm.a
|   fedora5:  -l/usr/X11R6/lib -lXpm

I don't think there is any conflit; just a bug in the way the LDFLAGS
are specified.  I don't think there should be any explicit mention of
libXpm.a.  That looks bogus to me.
