  5. # SYNOPSIS

  6. #

  7. #   AX_DIRNAME(PATHNAME)

  8. #

  9. # DESCRIPTION

  10. #

  11. #   Parts of the implementation have been taken from AS_DIRNAME from the

  12. #   main autoconf package in generation 2.5x. However, we do only use "sed"

  13. #   to cut out the dirname, and we do additionally clean up some dir/..

  14. #   parts in the resulting pattern.

  15. #

  16. #   this macro may be used in autoconf 2.13 scripts as well.
