To Phil, Arjen, and Greg:
@Phil:
There are some build issues with this commit on Linux that I found
once I switched to epa_built wxwidgets-3.0.2.
Here are the relevant error messages for the build. Note the location
/home/wine/newstart/build_script/install-linux is the install prefix
for epa_built software such as wxwidgets since I use my wine user
account both for general wine testing and also epa_building on Linux.

@Arjen and Greg: Note, I am pretty sure from the above results this
issue will show up for your comprehensive testing on Cygwin and
MinGW-w64/MSYS2. It also obviously blocks me from doing further wxwidgets
testing until it is fixed.
@Phil: Do you confirm the above build issues on one of the gcc
platforms (Cygwin, MinGW-w64/MSYS2, and/or Linux) accessible to you? I
assume some casts will take care of the wxUString overloading issues,
but I don't have a clue how to fix the last build error "error: taking
address of temporary [-fpermissive]" so I leave all of this to you to
figure out.
