Bug#805932: libsigc++-2.0-dev: Return-statement with a value, in function returning 'void'

[Riley Baird]

Package: libsigc++-2.0-dev
Version: 2.6.2-1
Severity: serious
Justification: Causes more than one other package to FTBFS

Hi,

I currently maintain granule. In the process of C++11 migration, I have come
across the following error message:

/usr/include/sigc++-2.0/sigc++/adaptors/adaptor_trait.h:256:21: error: return-
statement with a value, in function returning 'void' [-fpermissive]
{ return functor_(); }

I had thought that it was a problem with my package, but then I noticed that it
was also present in another, unrelated package (#805681), so I think that it
might be a problem with libsigc++-2.0-dev.

Thanks,

Riley
