Tidy up the document a bit to be more consistent in style. Add a
link to the mailing list discussion rather than keeping the text
inline, some of which is now no longer correct.

-Hi everyone,
-
-I think uClibc is a great project! And, since I found the file
-docs/uClibc_vs_SuSv3.txt in the source tarball which mentioned only
-fmtmsg as a missing function compared to the SUSv3, I got curious about
-the length of the list denoted by "<others?>". So I built the
-20040305-snapshot using allyesconfig, extracted the symbols from the
-(dynamic) libraries, and compared that list to the SUSv3 header files...
-
-The largest source of omissions was the mathematical interface
-(183/355), followed by optional interfaces (134/355). The result: only
-38 non-mathematical interfaces are missing compared to the minimal
-SUSv3! Naming only one function as missing was over-enthousiastic, but
-the result was better than I anticipated.
-
-A compact list of omissions is appended.
-I hope this was a helpful exercise ;)
-
-Greetings,
- Alexander

-P.S. uClibc was compiled with thread support, but did not provide the
-interfaces pthread_cleanup_push and pthread_cleanup_pop.

-Omissions from obligatory interfaces:
--------------------------------------
-stdlib.h: _Exit, lcong48, lldiv, posix_openpt;
- ecvt, fcvt
-ndbm.h: [all=9] dbm_*
-utmpx.h: [all=6] *utx* (but functions without "x" do exist!)
-nl_types.h: [all] catclose, catgets, catopen
-unistd.h: getwd, ualarm
-inttypes.h: imaxdiv

-string.h: strerror_r
-setjmp.h: setsigjmp
-monetary.h: strfmon
-sys/select.h: pselect
-sys/socket.h: sockatmark
-sys/wait.h: waitid
