I posted a article previously describing a problem I was having replacing
the C 6.0 RTL version of putchar() with my own, i.e. at link time I get
"multiply defined symbol" errors, in spite of me using the /NOD and /NOE
link options.  Well that was relatively easily worked around.
However the problem is much more serious than I thought.  I use MS Fortran
and MS C together in the same program (for better or worse).  This
requries that I link Fortran progs with both the LLIBFMT.LIB and LLIBCMT.LIB
files.  This worked fine with the C 5.1 libraries and linker.  However
now I get the "multiply defined symbols" error for all the functions common to the two libraries, the error the /NOE /NOD option is supposed
to suppress.... Result C6.0 is unusable!
 
The linker is MS Seg-Exe 5.10 and the link options I use are
/NOE /NOD /CO.  Anyone any idea what I'm doing wrong.  Everything worked
fine with Fortran 5.0 and C 5.1.......
