The problematic code is inlined from a wx API header, so I suspect not,
but maybe there's something in the rebuilt library too.

Even if the issue is header-only, it would definitely be good to retest
with 3.0.2-1 (in unstable only currently) in case there are changes in
the new upstream version which have solved this issue, especially as
Johan reports sage now builds OK.
