Here is an update:

The file can be compiled if the C code (that is commented as
such in the file) is cut out and placed in a separate
binary.c file. Then run mprep on the remaining file placing
the mprepped code into binarytm.c.

  mprep -o binarytm.c

I then compile the code using Borland C++ 5.0 IDE (using the
description on how to compile MathLink files for Windows systems as
described in the HELP section)

I've been successful in determining the source of the  "
MessageName::messg : OpenReadBinary::usage " error messages.. If all
the usage statements are deleted from the file prior to
running it through mprep... these messages no longer occur.

Which leaves the remaining error message -> ToExpression::sntx :
Syntax error in or before "    ...           ^".

In the file there are the 2 following Evaluates...

 resolveNewFilename[s_String] := 
    Module[{first = First[Characters[s]], colonpos, drive, os},



 resolveExistingFilename[s_String] := 
    Module[{first = First[Characters[s]], drive, os, fileinfo, 



which after mprep has been run -> get placed inside of if(_res)
statements .. inside of the binarytm.c file

If BOTH of these if(_res) statements are commented out of the
binarytm.c code..

The resulting executable links to Mathematica no problem...

   In[1] = Install["myfastbinary", LinkMode->Launch,   

   Out[1] = LinkObject[myfastbinary,2,2]

However, there is still one tincy wincy little problem.. The
OpenWriteBinary (etc.) routines require these functions to create
their links to the output files...

Anybody have any ideas?
