+ List of known bugs (certainly very incomplete)
+ ----------------------------------------------
+
+Time-stamp: <1997-03-20T02:33:37+0100 drepper>
+
+This following list contains those bugs which I'm aware of. Please
+make sure that bugs you report are not listed here. I you can fix one
+of these bugs I'll certainly be glad to receive a patch.
+
+Severity: [ *] to [***]
+
+
+[***] Profiling currently does not work with programs using NSS.
+
+[***] At least on Linux/Alpha, there seem to be problems with dynamically
+ loading NSS modules in certain situations.
+ [PR libc/137]
+
+[ **] For GNU libc on Linux, there is still no solution for the UTMP
+ problem.
+ [Among others: PR libc/39]
+
+[ **] There are problems with signal handling when using LinuxThreads.
+
+[ **] The `cbrtl' function is inaccurate. The algorithm used for `double'
+ and `float' is not usable.
+
+[ **] Not really a bug, but it could lead to such:
+ The RPC code is ugly ugly ugly. It's more or less verbatim taken
+ from Sun's code and therefore mostly lacks complete prototypes and
+ (more important) the use of `const'. It *definitely* needs to be
+ cleaned.
+
+[ *] The precision of the `sinhl' and/or `asinhl' function do not seem
+ to be the best.
+
+[ *] The syslog function should print to the console if the LOG_CONS
+ flag was given.
+ [PR libc/72]
+1997-03-20 01:49 Ulrich Drepper <drepper@cygnus.com>
+
+ * sysdeps/libm-ieee754/s_tanhl.c (__tanhl): Correct handling of
+ -inf.
+
+ * Makeconfig: (rpath-link): Add math/ directory.
+ (math-objdir): New variable.
+ (link-extra-lib): Define to special version when
+ $(common-objpfx)!=$(objpfx) to allow libraries outside
+ $(common-objpfx) be linked to the application.
+
+ * math/Makefile: Add rules to build and run test programs.
+ * math/libm-test.c (_GNU_SOURCE): Define only if still undefined.
+ (check_equal): Correct check for error.

+ (log_test): Fix typo.
+ (floor_test): Fix typo.
+ (pow_test): Fix typos.
+ (log10_test): Allow slight incorrectness for `log10(e)'.

+ (hypot_test): Rewrite test completely.
+ Patch partly by Andreas Jaeger.
+ * math/test-double.h (__NO_MATH_INLINES): Define only if not
+ already defined.
+ * math/test-float.h: Likewise.
+ * math/test-logdouble.h: Likewise.
+
+ * setjmp/setjmp.h: Change references of ANSI C to ISO C.
+ * setjmp/tst-setjmp.c: Correct and extend test suite.

+ * sysdeps/libm-ieee754/s_tanhf.c: Likewise.
+
+1997-03-19 21:13 Ulrich Drepper <drepper@cygnus.com>
+
+ * stdlib/strtod.c (STRTOL): Use wchar_t as type for `decimal' and
+ `thousands' to support systems with sizeof(wchar_t) !=
+ sizeof(wint_t). Blargh.
+
+ * sysdeps/unix/sysv/linux/socketbits.h: Remove definition of
+ SOL_IP, SOL_TCP, SOL_UDP, and SOL_IPX as they are defined in
+ appropriate headers.
+
+ * sysdeps/unix/sysv/linux/writev.c: Don't use MAX_IOVEC. Test for

+ Patch by HJ Lu.
+
+ * sysdeps/unix/sysv/linux/xstat.c: Include <kernel_stat.h>, not
