cwidget FTBFS with g++-4.4

[Steve Langasek]

The cwidget package fails to build in karmic because g++-4.4 is again more strict than previous versions of g++. The following debdiff fixes one issue with missing header includes, but after applying the patch the build still fails with the following error:

 g++ -DHAVE_CONFIG_H -I. -I. -I../../.. -I../../.. -Wall -Werror -I../../../src -g -O2 -D_REENTRANT -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -MT menubar.lo -MD -MP -MF .deps/menubar.Tpo -c menubar.cc -fPIC -DPIC -o .libs/menubar.o
cc1plus: warnings being treated as errors
/usr/include/sigc++-2.0/sigc++/limit_reference.h: In constructor 'cwidget::widgets::menubar::menubar(bool)':
/usr/include/sigc++-2.0/sigc++/limit_reference.h:81: error: dereferencing pointer '<anonymous>' does break strict-aliasing rules
/usr/include/sigc++-2.0/sigc++/limit_reference.h:81: note: initialized from here
make[5]: *** [menubar.lo] Error 1

I'm not sure if this is a bug in cwidget or in libsigc++-2.0; someone with deeper C++ knowledge than Iwill need to look at this.

debdiff to fix the first part of the build failure.
