commit: http://git.buildroot.net/buildroot/commit/?id=4297e7298edbef6dde75d8bf468441c6a242da5c
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/next
Building ncurses 5.9 with GCC 5.x fails with a syntax error, caused by
earlier preprocessing. This failure is more likely when building for
host (e.g. host-ncurses) that recently updated to GCC 5.x.
