I was wondering if someone could help me understand what is going
on with some problems with pcc that I am having.  I am running on
4.2BSD.

If I have a file which contains:

	unsigned a = (unsigned)5 >> 1;
	unsigned b = 5 >> 1;

then cc gives me the complaint:

	line 1: compiler error: expression causes compiler loop: try
		simplifying

and lint complains of an illegal initialization on that line.  The
construct on line 2 doesn't cause any problems.  Just declaring an
unsigned variable and doing the assignment as a statement also causes
no problems.

Also, I have a non-pcc based compiler that has no problem with this.

What gives?  Is this a known bug?
