branch: master
commit ba349aa32e98a53146794197c316f4765598ddbd
Author: Robert Pluim <rpluim@gmail.com>
Commit: Robert Pluim <rpluim@gmail.com>
Don't feed the awk scripts into themselves
* admin/unidata/Makefile.in (${unidir}/charscript.el,
${unidir}/emoji-zwj.el): Define variables for the required sources and
pass those to awk instead of $^, since the latter includes the awk
script itself.
