+wxWidgets 2 is designed to make use of WIN32 features and controls. However, unlike Microsoft,
we have not forgotten users of 16-bit Windows. Most features
work under Windows 3.1, including wxTreeCtrl and wxListCtrl using the generic implementation.
However, don't expect very Windows-95-specific classes to work, such as wxTaskBarIcon. The wxRegConfig
16-bit compilation is supported under Visual C++ 1.5, and Borland BC++ 4 to 5.

-This is under consideration, though we need to get wxWindows Unicode-aware first.

-by mostly cutting down wxWindows 2 API functionality, and adding a few classes here

-the statically-linked 'minimal' sample), shoehorning wxWindows 2 into a Windows CE device's limited

It's partly a matter of taste, but I (JACS) prefer Visual C++ since the debugger is very
good, it's very stable, the documentation is extensive, and it generates small executables.

Borland C++ is fine - and very fast - but it's hard (impossible?) to use the debugger without using project files, and
the debugger is nowhere near up to VC++'s quality. The IDE isn't great.<P>

If strange/weird/impossible things start to happen please
check (dumping IDE project file as makefile and doing text comparison

larger executables. It seems possible that the library can be created with
