I am writing my first DLL in BC++ 4.5 and am having some problems.  I have
written other DLL's in BC++ 2.0 and didn't have too much problem, although the
code in the DLL did not have any Windows related stuff in it.

The ultimate goal is to add some functionality to WordPerfect 5.2.  This the
same thing that I did with the last one I wrote.

I am starting up the learning curve by using the dlldemo project that comes
with BC++ 4.5.  I have the DLLSHELL.CPP in front of me and see the LibMain()
and the WEP() functions.  When I wrote the one in 2.0 I just included the
LibMain() and WEP() functions and then several _export functions and compiled
and linked it as a DLL file.

When I tried this in BC++ 4.5, I can't even get it linked.  The linker seems
to be looking for a definition for OwlMain(-----).  The only way I can get it
to link is to define a WinMain() function.  When I do this however, then
WordPerfect seems to complain that the resulting .exe is not a dll.  I have
the 16 bit Compiler Entry/Exit Code set to Windows DLL all functions exportable


What am I doing wrong here?  How can I get BC++4.5 to generate a .dll file?
Do I need WinMain() and LibMain()?  Why do I get the linker error when I
try to link without the WinMain()?
