Patch: warnings from interpret.cc

[Tom Tromey]

I'm checking in the appended patch, which eliminates a lot of spurious
warnings from the interpret.cc compilation.

2000-02-07  Tom Tromey  <tromey@cygnus.com>

	* interpret.cc (PUSHL): Don't use expression statement.
	(PUSHD): Likewise.
	(LOADL): Likewise.
	(STOREL): Likewise.
