The Win32s API set is a subset of the Win32 API so recompiling for non-Intel
environments will not result in any performance penalty when compared to the
Intel binary. Also it is not necessary to recompile a Win32s app for Intel
platforms. The same binary runs on Windows NT as a Win32 native application
and on Windows 3.1 as a Win32s application. In general the non-Intel
platforms are much faster than x86 architectures.
