[Mingw-users] Mingw GCC: Fortran to "C" conversion possible?

[Igor Mikolic-T. <ig...@al...>]

Get "f2c" at www.netlib.org.  It will convert Fortran into C.

If this is your goal, f2c will probably _not_ help you.  The tool generates 
C as a form of "portable assembler" -- it is not meant for human 
consumption.  Humans *can* read it (I have worked with it on many 
occasions), but it is never a fun experience.  I think that it will 
probably be quicker to learn to read Fortran than to make sense of the f2c 
output.  Fortran is actually rather easy to read -- with the exception of a 
handful of older statements (computed goto and arithmetic if), most of the 
control statements and expressions are relatively obvious.

Of course, YMMV.
