Subject: Use 3-arg form of AC_DEFINE instead of the
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a4635752052ccf24e702510836ed9ecd18d43464;p=pspp

Use 3-arg form of AC_DEFINE instead of the
AC_CHECK_FUNCS hack.  Now, it's still a hack, but at least the
comments in config.h.in are meaningful.
