  17 # Test that automake works around a bug of Solaris Make. The bug is the
  18 # following.  If we have a Makefile containg a file inclusion like this:
  19 #   include .//foo.mk
  20 # Solaris make fails with a message like:
  21 #   make: ... can't find '/foo.mk': No such file or directory
  22 #   make: fatal error ... read of include file '/foo.mk' failed
  23 # (even if the file 'foo.mk' exists). The error disappear by collapsing
  24 # the repeated slash '/' characters into a single one.
  25 #
  26 # See also "semantic" sister test 'subobj11a.sh', and related test
  27 # 'subobj11c.sh'.
