[ **] There are problems with signal handling when using LinuxThreads.

to be the best.

If you have some more measurements let me know.
+?? What version of the Linux kernel headers should be used?
+
+{AJ,UD} The headers from the most recent Linux kernel should be used.
+The headers used while compiling the GNU C library and the kernel
+binary used when using the library do not need to match. The GNU C
+library runs without problems on kernels that are older than the
+kernel headers used. The other way round (compiling the GNU C library
+with old kernel headers and running on a recent kernel) does not
+necessarily work. For example you can't use new kernel features when
+using old kernel headers for compiling the GNU C library.
+
?? When I run `nm -u libc.so' on the produced library I still
find unresolved symbols. Can this be ok?
?? What do I need for C++ development?
{HJ,AJ} You need either egcs 1.0.1 or gcc-2.8.0 with libstdc++
-2.8.0. libg++ 2.7.2 (and the Linux Versions 2.7.2.x) doesn't work very
+2.8.0. libg++ 2.7.2 (and the Linux Versions 2.7.2.x) doesn't work very
well with the GNU C library due to vtable thunks.
