Dialog Converter 3.4

While working on the BCX Getting Started Guide 3, I ran into an issue while compiling the example source code for Dialog Converter against Pelles C. When using Dialog Converter with the /l1 expand function names switch, it defines WinMain as int instead of int WINAPI.

Change log:
- Added return type for WinMain when using /l1 option
- Updated build.bat to use Pelles C instead of LCC-Win32
- Added blank afxres.h for vc example
