Tracked it down a bit more:

"Synchronize" is in /opt/lib/libX11.so and /usr/X11R6/lib/libXt.a,
but evidently the sizes don't match.

If I replace libX11.so with the one from the OS, then I get another
link problem because another couple of symbols are missing from the
LSB libc.

In other words, I'm programming in circles here.  I'm getting into
more and more dependencies on the OS libraries, fewer on the LSB
libraries.  At some point I may not be able to continue and still
maintain LSB compatibility, plus the executable will end up being
immense if I keep statically linking in libraries.

Is there a way out of this mess?
