Subject: Always check for HAVE_X11R5.
X-Git-Tag: emacs-19.34~491
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=f7894e88206bc3bb072057f285b1f1bc0c4c1fa3;p=emacs.git

Always check for HAVE_X11R5.
Separately decide whether to use a toolkit by default.

If X11R5 is missing the Xaw headers, default to --with-x-toolkit=no.

(powerpc-*-solaris2*): Use ibmrs6000, not rs6000.
