Hm, compiling with g++ 4.4 gave me a few compiling errors[0] - the patch 
attached "fixes" them, but when extundelete is actually used, it crashes:

# ./extundelete /dev/md0
Running extundelete version 0.0.3
extundelete: extundelete.cc:894: void load_super_block(struct_ext2_filsys*):
Assertion `(super_block.s_feature_compat & 0x0004)' failed.
Aborted

...but maybe that has been caused by the patch. Hm.

Christian.
