Subject: Test for XkbGetKeyboard with an AC_TRY_LINK whose
X-Git-Tag: emacs-pretest-21.0.95~403
X-Git-Url: http://git.eshelyaron.com/gitweb/?a=commitdiff_plain;h=9ca4be21c5e3f9fe07dab71b88b567ff6190350e;p=emacs.git

Test for XkbGetKeyboard with an AC_TRY_LINK whose
source file includes XKBlib.h.  On some broken Solaris systems,
there is an XKBlib.h, reportedly, but header files included by
XKBlib.h are missing.
