Yup, if "/usr/bin/cc" and "/usr/5bin/cc" produced code that worked the
same, Sun wouldn't have provided both of them.  X11 for Suns probably
shares lots of code written assuming BSD-style behavior, and as such
should be compiled in the environment that provides that behavior, i.e.
compiled with "/usr/bin/cc".

Why that causes streams buffers to be eaten up (which is what the
messages in question indicate happened) is another matter; perhaps the
miscompiled X server is misbehaving and not reading from the keyboard or
mouse file descriptors, and various flow control limits aren't set
appropriately to keep the system from running out of streams buffers in
that situation.
