For several weeks I've been seeing errors like this intermittently:

ERROR: Failed to make release
*** BUILD ABORTED ***

This is the very first mention of "csh.a" in the entire build.sh output.
I am seeing this error with MacOS X as the build host and one of my
coworkers is seeing it (and several other similar errors) with FreeBSD 6
as the build host.  I see it with -j values from -j2 to -j6; he sees it
even with -j1.

Is there some known synchronization problem with the Makefiles or nbmake
which doesn't occur with NetBSD as the host?
