Subject: configure: set HAVE___ATTRIBUTE__ for heimdal
X-Git-Tag: tdb-1.3.9~470
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1c796547f20fa3c7c2e93fd5ce6ee8453a2bb435;p=thirdparty%2Fsamba.git

configure: set HAVE___ATTRIBUTE__ for heimdal

Without this, heimdal ends up defining __attribute__ away, causing
gcc-6 compile errors with -Werror=return-type because it can't tell
when functions have __attribute__((noreturn)).
