Package: cdw Version: 0.7.1-1 Usertags: goto-cc During a rebuild of all packages in a clean sid chroot (and cowbuilder+pbuilder) the build failed with the following error. Please note that we use our research compiler tool-chain (using tools from the cbmc package), which permits extended reporting on type inconsistencies at link time.

As can be seen at
http://sources.debian.net/src/ncurses/5.9+20140118-1/include/curses.h.in?hl=455#L455
the _bkgrnd field is only included in struct _win_st if NCURSES_WIDECHAR is set
- which in turn is conditional as seen here:
http://sources.debian.net/src/ncurses/5.9+20140118-1/include/curses.h.in?hl=161#L161
Thus the use of #define _GNU_SOURCE in src/external_tools/cdw_ext_tools.c
implies inconsistent types. If _GNU_SOURCE is required, it should be set on the
compiler command line or in a project-wide include file to ensure consistency.
