|
|
dnl in generated configure script.
|
|
dnl
|

dnl distclean and maintainer-clean targets are modified

|
dnl to avoid unconditional removal of dependency subdirs
|

dnl which triggers distclean and maintainer-clean errors
|

dnl when using automake 'subdir-objects' option along

dnl multiple subdirs used for different build targets.

|
dnl New behavior first removes each dependency tracking
|
|
dnl file independently, and only removes each dependency
|
|
dnl subdir when it finds out that it no longer holds any
|
|
dnl dependency tracking file.
|
|
dnl
|
|
dnl When configure option --disable-dependency-tracking

dnl is used no amending takes place given that there are
