That gets me:

with this .def file:

   SioDone = _SioDone@4
   SioGetc = _SioGetc@4
   SioInfo = _SioInfo@4

   SioPuts = _SioPuts@12
   SioReset = _SioReset@12
   SioRxQue = _SioRxQue@4

Is there some command line option I can use to stop
the compiler from putting in these useless goofball numbers
in the first place?  A hexdump of wsc32.dll does not show
such numbers, nor does the created wsc32.lib.
A hexdump of the compiler .obj files is they only place
I find them.

Those "goofball numbers" are the Microsoft-defined standard windows calling convention. The fact that those get stripped for DLLs is another Microsoft invention that never made sense to me.

A hexdump is not a very good way to look at .obj files. Try using obj2asm or dumpobj. To look at import libraries, use lib to extract one of the modules in it, then use dumpobj or obj2asm on it.

It can really help to cut your project down. I suggest cutting it down to one export, one library being linked in, etc.

I created wsc32.lib using implib(_jk) from the wsc32.dll I was supplied.
Doing lib -x wsc32.lib SioBaud crated a 44 byte file.  Doing 'dumpobj SioBaud.obj'
told me what I already knew, the function is called "SioBaud".  Not _SioBaud,
not _SioBaud@8, just plain old "SioBaud".

All I'm doing is replacing wsc32.dll/wsc32.lib version 4.2 with wsc32.dll/wsc32.lib version 4.3.  I'm changing nothing in the working project.  With wsc32_42
I did not need any .def file, everything Just Worked.  I've tried
creating the wsc32.lib file with both implib and implib_jk with the same
results from wsc32.dll 43.

With wsc32_43 no combination of magic words in the .def file
will get the project to link.  It either tells me _SioBaud@8
is undefined, or "Error 81: Can Not Export _SioBaud@", or both.

What is "Error 81" truly telling me?

Then I suggest running lib over wsc32.lib and wsc32_42.lib to create wcs32.lst and wsc32_42.lst. Then, use lib to extract the .obj file from each that has SioBaud in it. Then, obj2asm or dumpobj each of those .obj files to see what is different.

I looked at the header files (wsc.h) and this MC declspec garbage. Maybe that is causing problems when you make the import lib?  Just force it all FAR PASCAL. =====================================================

#ifdef STATIC_LIBRARY
  #define DLL_IMPORT_EXPORT
#else
  #ifdef WIN32
    #ifdef DLL_SOURCE_CODE
       #define DLL_IMPORT_EXPORT __declspec(dllexport) __stdcall
    #else
       #define DLL_IMPORT_EXPORT __declspec(dllimport) __stdcall
    #endif
  #else
    #define DLL_IMPORT_EXPORT FAR PASCAL
  #endif
#endif

I've really *REALLY* learned to hate this crap.  I was happily
compiling with my version 4.2 DLL, everything was going fine.

Then I added add a new .cpp file to the makefile, related in no way at all to
the serial port DLL stuff, and now I get this:

Done.

9 errors, 0 warnings

Why did a adding a totally unrelated file break this
stuff again?

I'd like to simply work on my project, not continually
fight the tools...
