It was getting late, my laptop's battery was nearing its limit and I thought
perhaps some conflicting versions of the wxWidgets were being accessed. ldd,
though, did not show anything untowards. So then I focussed on the
MSVC/wxWidgets constellation ...
First disappointment: a quick search did not bring up any ready-made
distributions but instead the advice to build it yourself from source. So I
tried this. And that was the second disappointment. There is a so-called
solution (MicroSoft's answer to makefiles) in the source distribution I
retrieved, so I could load it into Visual Studio (whereas the wxWidgets Wiki
described only the now virtually extinct Developer Studio, which uses a
different approach). Building the solution (that is: the set of libraries)
quickly brought up 92 compile errors of the type:
..\..\src\stc\scintilla\lexers\LexA68k.cxx(131): error C2664:
'StyleContext::StyleContext(unsigned int,unsigned int,int,LexAccessor &,char)'
: cannot convert parameter 4 from 'Accessor' to 'LexAccessor &'
Not the sort of things I enjoy debugging.

That is certainly worth a try

Seen that. I will write a short reply - the annoying thing is that this is only
detected at run-time, not at build-time.
