Description: avoid if preprocessor when macro contains a cast
 Version 5.9+20140118 embeds an explicit cast to chtype
 inside macros like A_STANDOUT.
 The GCC preprocessor does not recognize the chtype identifier
 and replaces it with 0, making the test fail with an error message.
 .
 Upstream will decide if curses.h should be reverted
 or this patch permanently applied to gen.c.
