Summary: configure: curses busted on Freebsd/Mac OSX

Initial Comment:
Anthony said to log this:



checking ncurses.h presence... yes

configure: WARNING: ncurses.h: present but cannot be 

compiled

configure: WARNING: ncurses.h: check for missing 

prerequisite headers?

configure: WARNING: ncurses.h: proceeding with the 

preprocessor's result

configure: WARNING:     ## 

------------------------------------ ##

configure: WARNING:     ## Report this to bug-

autoconf at gnu.org. ##

configure: WARNING:     ## 

------------------------------------ ##



I'll attach the text of the report and the configure output 

too since I'm pretty sure the above won't be ligible once 

sf's tracker's finished with it.

Unless a FreeBSD or Mac OS X expert can step forward in the

next day and suggest a fix, this isn't going to be fixed for

2.3.2(final). I can't spend any more time on it.

The diagnosis on OS X is similar, and the trigger for defining wchar_t in 
stdlib.h is the absence of _ANSI_SOURCE. 
 
Making it not define _XOPEN_SOURCE_EXTENDED also fixes the compile 
as per your FreeBSD fix.

Looking into it a bit on FreeBSD:

/usr/include/ncurses.h:236: conflicting types for `wchar_t'

/usr/include/stdlib.h:58: previous declaration of `wchar_t'



and poking around a bit I find that stdlib.h defines wchar_t

as an 'int', while ncurses.h defines it as 'unsigned long'. 



This is on FreeBSD 4.8. 



Extracting the failing configure code and making it not

define _XOPEN_EXTENDED_SOURCE makes the test succeed, but I

have no idea if this is an appropriate fix.

(I didn't mention it in the report, only to Anthony : this is on 

OSX)



The patch doesn't alter the configure behaviour.



I can't remember how to run the curses test - "make test" skips 

it (the curses module is built though).

Can you try the patch in python.org/sf/806800 ?

"make test" also reports:



test_curses

test test_curses crashed -- _curses.error: curs_set() returned 

ERR

creosote (which is a freebsd machine) also sees this.
