Subject: convert BAD_RANGE() to an inline function
Date: Sun, 2 Jun 2002 15:15:30 -0700 [thread overview]
Message-ID: <20020602221530.GM14918@holomorphy.com> (raw)
BAD_RANGE() is too complex to merit being a macro definition. The
following patch converts it to an inline function.
Against 2.5.19.
Cheers,
Bill
