\f
Version 2.16
incorporated into an official GNU C Library release.
When working with Linux kernels, this version of the GNU C Library
-requires Linux kernel version 2.6.0 or later.
-
-All Linux kernel versions prior to 2.6.16 are known to have some bugs that
-may cause some of the tests related to pthreads in "make check" to fail.
-If you see such problems, please try the test suite on the most recent
-Linux kernel version that you can use, before pursuing those bugs further.
+requires Linux kernel version 2.6.16 or later.
Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.
