+Whether this defect report also applies to a natively-build GCC from SVN trunk
+has not yet been checked.
+
+[[Thomas_Schwinge|tschwinge]] suspects the problem to be a configuration issue
+of a GCC helper library, whose configuration setup has changed after GCC 4.3.
+
+The need for `-lpthread` is another story.  See the Debian glibc patches
+repository for details.

+
+This todo is primarily targetted at the Hurd proper
+and applications that rely on the Hurd interfaces.
+
+* psmisc
+
+The tools provided by the psmisc package are linux centric. Killall and pstree, for instance, require Linux's proc file system but could just as easily use Hurd's libps.
+
+* tmpfs
+* ppp
+* unionfs/stowfs
+* supermount translator
+
+Related: [[KnownHurdLimits]]
+
+From Marcus, 2002:
+
+* xkb driver for console (for international users)
+* kbd leds in console (well, in general, Roland's new driver in oskit for that crap)
+* fixing fakeroot (it's buggy)
+* fixing tmpfs (it's buggy, Neal says it's Mach's fault)
+* adding posix shared memory (requires the io\_close call to be implemented)
+* adding posix file locking (requires the io\_close call to be implemented)
+* testing
+  * find + various filesystems (are inode numbers for . and .. sane?)
+  * ext2fs with other block sizes than 4096
+  * --help and --version and --usage in all programs
+    * I have seen ^V in some --help output, might be argp bug
+    * Verify that all options are documented clearly, and that no unimplemented options appear
+    * Is the short and long description in the help output correct?
+  * Is the return value of all programs correct (eg, does main() return a sane value)
+  * Is the suid bit correctly set for all installed programs?
+  * Translators
+    * Does settrans -g work? -fg?
+    * Does fsysopts work? Does setting options with fsysopts work?
+    * Does stat() work on all translated nodes and give proper data?
+    * What about chown, chmod (some translators should pass this through to the underlying node, esp in /dev!)
+    * Does statfs give correct data?
+    * Are all inode numbers and link counts correct?
+* We also should have a "make check" test suite. We can add this once Jeff finished his automake patches
+* pick up the other things
+  * pthread, definitely. Now that we are so close
+  * new console is basically done
+    * needs integration of course
+    * X switching support
+* there is certainly more to do ...
