+ We need to:
+ - make a minimal distribution under wx/src/xmhtml, just enough
+ to compile the source.
+ - add XMHTML_C_SRC to src/motif/makefile.unx with the source files
+ listed.
+ - make sure we can compile the sources, passing the correct
+ flags for zlib/png compilation.
+ - make a wxHTMLWindow class from e.g. examples/example_2.c. Should
+ probably make the cache and history facilities part of the class.
+ - add the driver code to src/motif/helphtml.cpp (a frame, toolbar,
+ history list).
