 I wanted to fix these warnings in wxWidgets itself, but before fixing them
I wanted to reproduce them -- and totally failed to do it. I've tried
building the files including the specified headers using the same warning
options lmi uses, with both -O0 and, when this didn't work, -O2, with g++
10.1 from Debian Sid, but I just don't see any warnings at all.

 Could you please let me know which compiler command lines result in these
warnings appearing?

 Thanks in advance!
