Bug#649164: getconf: missing POSIX_V7_THREADS_CFLAGS, POSIX_V7_THREADS_LDFLAGS variables

[Jonathan Nieder <jrnieder@gmail.com>]

Package: libc-bin
Version: 2.13-21
Severity: wishlist
Justification: POSIX.1-2008 XCU.c99 extended description, table 4-6
Tags: upstream

Hi,

POSIX says:

	In addition to the type size programming environments above,
	all implementations support a multi-threaded programming
	environment that is orthogonal to all the programming
	environments listed above. The getconf utility can be used to
	get flags for the threaded environment, as indicated in
	Table 4-6.

and continues by documenting that

	getconf POSIX_V7_THREADS_CFLAGS
	getconf POSIX_V7_THREADS_LDFLAGS

retrieve the compiler flags and linker flags, respectively, for
building multithreaded programs.  glibc getconf does not seem to
support this.

Certainly not urgent, but thought I should report it before I forget.

Sincerely,
Jonathan

(Side note: on amd64, "getconf -v POSIX_V7_LP64_OFF64 POSIX2_VERSION"
works but "getconf -v POSIX_V7_ILP32_OFF32 POSIX2_VERSION" produces
"getconf: Couldn't execute /usr/lib/getconf/POSIX_V7_ILP32_OFF32: No
such file or directory".  So something seems awry, though I care even
less about it.  Please let me know if you would like a report about
that.)
