Subject: min/max and all that jazz
Date: Wed, 19 Sep 2001 11:59:17 +0200 [thread overview]
Message-ID: <20010919115917.A12129@maclaurence.math.u-psud.fr> (raw)
gcc has a warning option -Wsign-compare (not turned on by -Wall):
`-Wsign-compare'
Warn when a comparison between signed and unsigned values could
produce an incorrect result when the signed value is converted to
unsigned. This warning is also enabled by `-W'; to get the other
warnings of `-W' without this warning, use `-W -Wno-sign-compare'.
This might pick up some errors of the kind the new min/max macros
are trying to catch...
Duncan.
