Subject: 1.5.5.1 sysconf() NOT implemented for _SC_STREAM_MAX and _SC_TZNAME_MAX?

Hi all,

I found some problem in sysconf() system call with respect to following
assertions defined in "IEEE std 2003.1 -1992 Test methods for measuring
conformance to POSIX-part1" document


10(A)	 If STREAM_MAX is defined when the header <limits.h> is included:
	A call to sysconf(_SC_STREAM_MAX) either returns -1 without changing errno
	or returns a value greater than or equal to {STREAM_MAX}.
Otherwise:
	A call to sysconf(_SC_STREAM_MAX) either returns -1 without changing errno
	or returns a value greater than or equal to {_POSIX_STREAM_MAX}.
 
11(A)	 If TZNAME_MAX is defined when the header <limits.h> is included:
	A call to sysconf(_SC_TZNAME_MAX) either returns -1 without changing errno
	or returns a value greater than or equal to {TZNAME_MAX}.
Otherwise:
	A call to sysconf(_SC_TZNAME_MAX) either returns -1 without changing errno
	or returns a value greater than or equal to {_POSIX_TZNAME_MAX}.

********when called with argument _SC_STREAM_MAX or _SC_TZNAME_MAX, It
returns -1 but set errno to 22 (EINVAL) but is should not modify its 
value.
 
By looking into code, I found that sysconf() is not implemented for these
argument values! Is any one going to address these in near future?


Thanks and regards,

ghanshyam
