    Merge branch 'master' into ng/master

    * master:
      tests: remove stray uses of 'Exit', in favour of simple 'exit'
      general: assume dot-starting file names are supported
      Drop support for DJGPP, MS-DOS, Windows 95/98/ME
      depcomp: remove support for SGI C/C++ compilers
      tests: a test about warnings in category 'obsolete' was failing spuriously
      ACLOCAL_AMFLAGS: fully deprecate, with warnings in the 'obsolete' category
      compile: remove support for $(INCLUDES)
      aclocal: allow third-party macros take precedence over automake ones
