Description Owen Taylor 2004-11-02 16:34:37 UTC 
Unless you supply --disable-threads to configure, libX11 will be
built with threading support, XTHREADS is defined by the configure.ac.

But all the other libraries making up 'xlibs' are built without,
so LockDisplay(), and so forth, compile to no-ops.

One fix would be to, when libX11 is built with threading support,
add -DXTHREADS to Cflags in X11.pc. This would also help apps
that use XlibInt.c.
Comment 1 Josh Triplett 2005-05-05 00:22:42 UTC 
An alternative fix was added to libX11 some time ago: Xlibint.h is now generated
from Xlibint.h.in, with "#define XTHREADS" added if libX11 was built with XTHREADS.
