When I build defrag, (with gcc 4.1) then I see these errors:
cc1: warnings being treated as errors
e2dump.c: In function ?dump_super?:
e2dump.c:474: warning: dereferencing type-punned pointer will break
strict-aliasing rules

e2dump.c:516: warning: dereferencing type-punned pointer will break

After fixing them everything builds fine... (patch attached)
