[ANNOUNCE] libpthread-stubs 0.1

The XCB developers have introduced a new library, libpthread-stubs. This
library provides weak aliases for pthread functions not provided in libc
or otherwise available by default. Libraries like libxcb rely on pthread stubs
to use pthreads optionally, becoming thread-safe when linked to libpthread,
while avoiding any performance hit when running single-threaded.
libpthread-stubs supports this behavior even on platforms which do not supply
all the necessary pthread stubs. On platforms which already supply all the
necessary pthread stubs, this package ships only the pkg-config file
pthread-stubs.pc, to allow libraries to unconditionally express a dependency
on pthread-stubs and still obtain correct behavior.
This initial 0.1 release provides the pthread stubs needed by libxcb.
Known issue: Some platforms supply extern inline pthread functions in a
pthread header, the internals of which do not cooperate with libpthread-stubs.
We plan to work around this in future versions of libpthread-stubs. For now,
you can work around the problem in software which includes pthread.h by
#defining __NO_INLINES__ or by turning off optimization.
