-Borland precompilation is largely automatic. Visual C++ requires specification of {\tt "wx/wxprec.h"} as
-the file to use for precompilation. Watcom C++ is automatic apart from the specification of
-the .pch file. Watcom C++ is strange in requiring the precompiled header to be used only for
-object files compiled in the same directory as that in which the precompiled header was created.
-Therefore, the wxWidgets Watcom C++ makefiles go through hoops deleting and recreating
-a single precompiled header file for each module, thus preventing an accumulation of many
-multi-megabyte .pch files.

This sounds like facetious advice, but it is surprising how often people
don't use a debugger. Often it is an overhead to install or learn how to
use a debugger, but it really is essential for anything but the most
trivial programs.
