Re: autoreconf 2.53 does not handle three levels of configure.ac

[Akim Demaille]

| autoreconf scans configure.ac files for AC_CONFIG_SUBDIRS and adds the
| directory to the list of directories to recusively run autoreconf
| in. Unforuntaley, when the subdir is decended into and
| AC_CONFIG_SUBDIRS is discovered, the current directory is not
| prepended onto the subdir name - resultsing in failure. Therefore
| something like:
| 
| |-configure.ac
| |-foo
|     |configure.ac
|     |bar
|        |configure.ac
| 
| results in autoreconf trying to run autoconf in ".", "foo" and "bar"
| instead of "foo/bar"
| 
| The following patch solves the problem and should work under windows as well.

Thanks.  I'm applying this instead:
