# If we have a Makefile containing a file inclusion like this:
#
# include .//foo.mk
#
# Solaris 10 make fails with a message like:
#
# make: ... can't find '/foo.mk': No such file or directory
# make: fatal error ... read of include file '/foo.mk' failed
#
# (even if the file 'foo.mk' exists). Our dependency tracking support
# code used to generate include directives like that sometimes, thus
# causing spurious failures.
#
# GNU make shouldn't suffer from that Solaris make bug, but we check
# the problematic setup anyway -- better safe than sorry.
