ieee_flags

[Paul W Campbell]

I am trying to build some very old ( circa 93-97) Fortran
and I am getting some undefined references.
I have googled, crawled FAQs, actually re-read the docs for make,
and man for gfortran. I noticed some mention in 1992, 2002 in news
but it did not seem relevant.

I had commented thisout previously but wonder if they were the 
cause of a seq fault. So, now, I am looking for a way to resolve
this references.

Any suggestions or magic incantations ?

  call IEEE_FLAGS("clearall","exceptions","all","")


<- snipped from makefile ->
FFLAGS = -g -C

         $(FC) $(FFLAGS) $(LDFLAGS) $(LOADLIBES) -o $@ $(z3f-objs)

(same result with/without ieee=full )
