#14250: libgnt fails to compile on OS X 10.6.7 due to missing cchar_t

 Reporter:  elb                  |     Owner:  sadrul
     Type:  defect               |    Status:  new   
Component:  finch (gnt/ncurses)  |   Version:  2.7.11
 Keywords:                       |  
---------------------------------+------------------------------------------
 gntwm.c contains this macro:

 {{{
 #ifdef USE_PYTHON
 #include <Python.h>
 #else
 #define _GNU_SOURCE
 #if (defined(__APPLE__) || defined(__unix__)) && !defined(__FreeBSD__) &&
 !defined(__OpenBSD__)
 #define _XOPEN_SOURCE_EXTENDED
 #endif
 #endif
 }}}

 This fails to define _XOPEN_SOURCE_EXTENDED on OS X if USE_PYTHON is
 defined.  Without _XOPEN_SOURCE_EXTENDED, ncurses.h does not include
 cchar_t on OS X, and the multi-cell character workaround will not compile.

 Rather than simply moving this check out of the USE_PYTHON block or adding
 a second check for OS X, I figured I should see if anyone knows why this
 check is structured as it is.

 2.8.0 will not compile on OS X without a fix for this.  I am not sure if
 2.7.11 will or not; I had never encountered this failure to compile before
 recently, but the checks in question are quite old.  (They haven't been
 changed at all since Jan 2009.)
