wine/dlls/dbghelp/minidump.c
Eric Pouech 7ea69cc7ea - Various improvements for minidump module information
. added timestamp & checksum in PE module
  . added size & checksum in ELF module
  . wine loader now appears with its pathname.
- Implemented PE & ELF timestamp & checksum validation in
  SymFindFileInPath.
