When trying to install python2.3 on either stable or current the 
curses module doesn't build. I get the following compiler complaints:

STABLE (line numbers in brackets are from CURRENT)
 
/usr/include/ncurses.h:236(289): conflicting types for `wchar_t'
/usr/include/stdlib.h:58(57): previous declaration of `wchar_t'
/usr/include/ncurses.h:239(292): conflicting types for `wint_t'
/usr/include/wchar.h:89(96): previous declaration of `wint_t'

Can somebody explain what the differrence between_WCHAR_T and _BSD_WCHAR_T
 is? I appended relevant parts of these header files from STABLE.

Simply deleting lines 234-240 of /usr/include/ncurses.h works 
(The curses module builds without problems.) However I would much 
rather learn the reason for the various definitions of wchar_t
