(original bugreport at the end of the mail, fullquote by intention)
I just investigated on this FTBFS issue.

The commit message talks about EXT2FS_OLD_32_COMPAT which should
provide compiling of "Old-style applications who don't want to

implemented in this commit nor in a following one.
The code of extundelete that's failing to compile is:
The issue was brought up on the mailinglist of extundelete a few
weeks ago, but there wasn't a reaction from upstream since then.
Eric and Theodore - any ideas what's the best way to resolve this
issue in the meanwhile?
