 Oh, it is there alright, but not documented in the info files (RH must
 be rolling their own man-pages?).  Follow "stdlib/wcstombs.c" to
 "wcsmbs/wcsrtombs.c", search for "NULL special".  No mention of why
 they do it, though.
 
 MSVC++ 6.0 does it too (might be a hint where it comes from :-( ).
 Finally, I did find another system that does not handle the NULL case,
 according to its documentation at least: DEC (i.e. Compaq whatever).
 
 Never mind.
