Bug#804736: libwfut: FTBFS: sigc++/object_slot.h: No such file or directory

[Aaron M. Ucko]

Source: libwfut
Version: 0.2.3-2
Severity: serious
Justification: fails to build from source (but built successfully in the past)

Hi, Olek.

Automated builds of libwfut have been failing with errors of the form

  libtool: compile:  g++ -DHAVE_CONFIG_H -I.. -I/usr/include/python2.7 -D_FORTIFY_SOURCE=2 -g -O2 -fstack-protector-strong -Wformat -Werror=format-security -O3 -DNDEBUG -DTIXML_USE_STL=1 -std=c++11 -I/usr/include/sigc++-2.0 -I/usr/lib/aarch64-linux-gnu/sigc++-2.0/include -c WFUT.cxx  -fPIC -DPIC -o .libs/WFUT.o
  WFUT.cxx:3086:32: fatal error: sigc++/object_slot.h: No such file or directory
compilation terminated.

The only sigc++/object_slot.h I see is from sigc++ 1.2.  Could you
please take a look?

Thanks!
