gfortran, ncar and blockdata_test failures

[Jack Howarth]

Walter,
   Now I am confused. I hadn't realized that gfortran was passing
this test passes under linux i386 and x86_64. Does the linux linker
do something to explicitly make this work or is it just a happy
accident? Perhaps a radar report could be opened against the Darwin
linker if we knew what had to be done to fix the issue linker-side.
