c++.windows.32-bits - Making a DLL

My initial attempts simply used the '-mn -WD' options and listed the code files.
When that failed, I fired up the IDDE and set up a Win32 DLL project.  In both
cases, I get the same giant list of errors involved being unable to export
symbols.

I am sure that I'm just doing something foolish.  In particular, I have not
added GDI32.lib and other system libraries that I need to build the project.  I
don't directly see how that would cause the "cannot export" errors, but I
certainly see how it would cause the "undefined" errors.

Here is an abbreviated example of the output.  I cut out most of my member
functions, because they were boring.  I left the "undefined" errors for the
various library functions alone, in case those were somehow useful.  Any
suggestions would be greatly appreciated.

Never mind...  After I included gdi32.lib, kernel32.lib, and comdlg32.lib on my
build line, the imports worked and, suddenly, the exports were perfectly happy.
Don't know why, but it works, and I've got a DLL.

Sorry for the wasted bandwidth.
