I have found that f2cx + gcc/DJGPP makes a Fortran system on a PC which
is not only easy to use but produces code which executes faster than
several commercial F77 compilers.  

But I have found one minor problem: a Fortran OPEN(STATUS='OLD' does not
return an error status when one tries to open a file which does not exist,
as one would normally expect.  The INQUIRE statement, however, does report
correctly on non-existent files.  It's clear that the problem lies in the
implementation of OPEN in libI77: I have tried recompiling the whole
library with and without defining MSDOS and NON_UNIX_STDIO but to no
avail.  If anyone else has come across this problem and solved it, I'd be
grateful any help.
