Does the application "manually prototype" any of these missing
functions?  That might cause these symptoms.  In C++, one must include
the appropriate header instead of writing your own prototype.

If that's not it, if you could reproduce this in a small but complete
demo, I'm sure we could figure it out.

Be sure you are using the right prefix file.  

Also I would think that perhaps you may be mixing the headers and 
precompiled headers up or something.

Finally do you have any other libraries included perhaps they need to be 
rebuilt.  If they were built and linked with a pow() or fabs() that are 
listed as extern  and now they are inlined that can cause a problem.

If you can narrow this down to a smaller project it might help, but I'm 
thinking this is very likely from an older library that is being linked 
in.

What prefix file should I be using? Im using a custom one by the makers of a
specialized plugin SDK.

I've only included the regular Win libraries. Kernel32, user32... I have
also included the 3 icm libraries, but I get the link errors without them.

I really don�t see how I can narrow this down. I really wish I could. If I
create a small app that does a floor, abs and a few other math routines that
are currently not linking correctly, they link without any problem with the
same libraries.

Without info stating explicitly to the contrary, the parts that need to
be compiled as C ought to be compiled by a C compiler (hint: macro
__cplusplus and/or other vendor specific definitions).

If the parenthesised text represents mangled names on your compiler then
yes.

<gut feeling>
Change the parts responsible for invoking the compiler upon *.c files
such that said files get a C compilation.
</gut feeling>

All I can think of is using a preprocessed file and seeing if that helps 
it.  you may want to use a link map and see what is being linked in.  
Other than that I'm stymied without some sort example I can look at.
