   1 Fix GCC 5.x preprocessor failure
   2
   3 Building ncurses 5.9 with GCC 5.x fails with a syntax error, caused by
   4 earlier preprocessing. This failure is more likely when building for
   5 host (e.g. host-ncurses) that recently updated to GCC 5.x.

   7 This patch is taken from the following link (more information is also
   8 available here):
