[New-bugs-announce] [issue28190] Cross-build _curses failed if host ncurses headers and target ncurses headers have different layouts

[Chi Hsuan Yen]

New submission from Chi Hsuan Yen:

In changeset 919259054621 (from issue12567) and 707761d59a4a (from issue15268), /usr/include/ncursesw was added to include paths in setup.py and configure.ac. This is wrong and breaks cross-compiling. For example, if   host has /usr/include/ncursesw/ncurses.h and target has $SYSROOT/include/ncurses.h, the build fails. An example can be found in [1].

My patch removes all references to /usr/include/ncursesw and uses a robust detection, which is suitable for both native builds and cross builds.

Added the authors of aforementioned changesets.
