Subject: [PATCH] Port better to QNX
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Problem reported by Elad Lahav on emacs-devel.
* configure.ac: On QNX, default CC to qcc (a GCC wrapper),
and default LDFLAGS to -N2MB so that the initial stack size
is not too small.  Also, fix misspelling of ‘qnxnto’.
