No, I tried this too, doesn't work.

	(gdb) set var=0
	A syntax error in expression, near `=0'.

But, it turns out I choosed a bad name for the variable when
I tested the fix in unxex().

	(gdb) set xxx=0

This works.

	(gdb) set var var=0

This works too. I guess, when gdb sees "set var" it expects the
full "set variable ..." command.

Oleg.
