Please unblock package wxwidgets3.0
The package was recently binNMUed, apparently to enabled PIE (which gcc
now defaults to). However gcc now also defaults to C++11, which results
in wx's headers in the binNMU not being usable for applications
compiling as C++98. This broke qutemol (which forces building as C++98
to work around C++11 incompatibilities) and may well break other rdeps -
without a mass rebuild to check we can't know.
The debian bug (severity serious) is:
https://bugs.debian.org/856350
Adrian Bunk proposed explicitly forcing C++98 mode when building
wxwidgets3.0, which seems a prudent choice for stretch - it essentially
returns us to the pre-binNMU situation.
Here is the complete debdiff against the version in testing:
