Pardon me if this has already been covered.

A user has been benchmarking f77 with various fpa options on a Sun 3/280.
He took a simple REAL benchmark, changed some types to COMPLEX and DOUBLE
COMPLEX types , and noted a slowdown by a factor of about 90.  The obvious
assumption is that the COMPLEX library code doesn't use the FPA.

I haven't looked deeply into this (i.e. I scanned TFM but didn't note
anything relevant). (I'm not that interested in Fortran.)

For the f77 hackers:
    Am I missing something ?
    Should this occur ? 
    Is this a known bug ? 
    Is there anything I can do about it ?
