That's what I figured, but I also figured it was marginally better to be
pedantic in case WXPREF was used somewhere other than via the command line.

What file defines wxEvent? You must surely have a .o file which defines it
as an exportable symbol.

An example from (wxPython's internal) wxGTK with the no_rtti and
no_exceptions flags set:
c++ -c -I./lib/wx/include/gtkd-2.3 -I../include -I../src/zlib \
-I../src/png -I../src/jpeg -I../src/tiff -I/usr/include/gtk-1.2 \
-I/usr/include/glib-1.2 -I/usr/lib/glib/include -D_REENTRANT \
-I/usr/X11R6/include -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES \
-D__WXGTK__ -D__WXDEBUG__ -fno-rtti -fno-exceptions -O2 -MMD -pthread \
-Wall -fPIC -o brush.o ../src/gtk/brush.cpp
Here's one from wxPython:
gcc -DNDEBUG -O3 -fPIC -DSWIG_GLOBAL -DHAVE_CONFIG_H -DWXP_USE_THREAD=1 \
-Isrc -I/usr/local/include/python2.3 -c contrib/dllwidget/dllwidget.cpp \
-o build/temp.linux-i686-2.3/dllwidget.o \
-I/usr/local/lib/wx/include/gtkd-2.3 -D__WXDEBUG__ -D__WXGTK__ \
-D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -fno-rtti -fno-exceptions \
-I/usr/include/gtk-1.2 -I/usr/include/glib-1.2 -I/usr/lib/glib/include \

Just tried that. Running wxPython/demo/demo.py now yields:

undefined symbol: Eof__C13wxInputStream
which c++filt reports as
The original __ti7wxEvent symbol is no longer to be found anywhere (defined
or referenced). Eof__C13wxInputStream is referenced from
Ah, wait a minute. I see a likely candidate for the screwup:
% type c++
c++ is /usr/local/bin/c++
% c++ --version
% type gcc
gcc is /usr/bin/gcc
% gcc --version
Does mix-n-match across GCC versions strike you as a plausible reason for
the errors? I am rebuilding while I await your reply...
