Subject: Make __typeof__-using code depend on HAVE_TYPEOF, not __GNUC__,
X-Git-Tag: CPPI-1_12~1281
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=4ef7ce47dc621209b97bc6074844ea7d290f8286;p=thirdparty%2Fcoreutils.git

Make __typeof__-using code depend on HAVE_TYPEOF, not __GNUC__,
since so many other C compilers also honor __typeof__.
