Subject: [Patch] libguile/gc-card.c: A cast does not yield an lvalue
Date: Wed, 18 Jun 2003 08:56:05 +0200 [thread overview]
Message-ID: <uw5ptlbswl6.fsf@saturn.math.uni-magdeburg.de> (raw)
When compiling Guile from CVS HEAD with the Sun Forte C compiler, I
get the error "A cast does not yield an lvalue" when compiling
gc-card.c.
Here is a patch. (See also the ChangeLog entry of 2001-01-11.)
