WARNING: [check-portability.awk] => Found $RANDOM:
WARNING: [check-portability.awk] configure:       INTLTOOL_XML_NOMERGE_RULE='%.xml:       %.xml.in       $(INTLTOOL_MERGE) ; $(INTLTOOL_V_MERGE)_it_tmp_dir=tmp.intltool.$$RANDOM && mkdir $$_it_tmp_dir && LC_ALL=C $(INTLTOOL_MERGE) $(INTLTOOL_V_MERGE_OPTIONS) -x -u $$_it_tmp_dir $< $@ && rmdir $$_it_tmp_dir'

Explanation:
===========================================================================
The variable $RANDOM is not required for a POSIX-conforming shell, and
many implementations of /bin/sh do not support it. It should therefore
not be used in shell programs that are meant to be portable across a
large number of POSIX-like systems.
