Subject: Define isinf macro only if it is not defined as a macro, even if
X-Git-Tag: v0.6.0~560
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=470affdb48180aebfa764941bbdb353062978444;p=pspp-builds.git

Define isinf macro only if it is not defined as a macro, even if
!HAVE_ISINF, because mingw seems to have the macro without the
function.
