When I conditionally set F77LINK=$(LINK), automake complains.
# Makefile.am snippet
if NOFORT
F77LINK = $(LINK)
endif

automake: F77LINK was already defined in condition NOFORT, which is included in 
condition TRUE ...
Makefile.am: 2 ... `F77LINK` previously defined here

Although inadvisable, I thought the Makefile.am could override whatever it 
wanted, without warning.  See 23.1 Extending Automake Rules in the automake 
manual.

If I remove the AM_CONDITIONAL use and simply have F77LINK = $(LINK), automake 
no longer complains.  This doesn't seem correct.  In any case, I do need to 
conditionalize this assignment.  For example, I'm not quite sure how I could 
use AC_SUBST in this case in order to avoid the use of the conditional.  
Something to the effect of AC_SUBST([F77LINK], [[$(LINK)]]), if you know what 
I'm trying to get at here.  (I apologize, I don't know what you meant by 
Makefile-global, if there is some other means of accomplishing what I want.)

Thanks,
Jeff
