I have had a fair amount of trouble with the absoft compiler, including
finding one bug that they blame on the 68040 chip. On the other hand
I have had no problems with f2c (available free on ftp sites) AND
programs tend to run quicker if I use f2c rather than the absoft
compiler. 
The absoft compiler is certainly fine for simple fortran but if
(like me) you have 300 subroutines of ancient fortran using all
sorts of dubious constructs, then forget it. For example, if you
have a subroutine that has entry points that allow an alternative
return code (ENTRY MYENTRY(A,*) syntax) then the subroutine itself
must be declared MYSUBROUTINE(...,*) even if the main subroutine 
does not use alternate returns. Similarly, absoft compiler is
annoyingly picky about where data statements can appear ( having
to change several hundred routines to fix this was also a pain).
