   Perhaps you would be more concerned if you weren't compiling on a
   Cray-2?  One weakness of the standard (it seems to me) is that it seems
   to be designed for extremely powerful machines.  A lot of FORTRAN code runs
   on machines several orders of magnitude slower than a CRAY-2.  While the
   difference between compilation times of 10 seconds and 100 seconds may
   not be enough to worry about, the difference between 2 minutes and 20
   minutes --- the same factor of 10 --- is the difference between a
   quick stretch and a long coffee break.

Most of the time spent in such a compiler is the optimizer. If you
don't have a fancy vector processor and a complex set of related
functional units, compilation goes very quickly.

The difference between 2 minutes and 2minutes 45 seconds may feel like
forever, but with f88 you might not need such big source files.
