Last change on this file since 22020 was 22020, checked in by dmik, 13 years ago

Disable debug fields of RTL_CRITICAL_SECTION_DEBUG.

Odin uses the DebugInfo ptr in CRITICAL_SECTION for its own purposes
which are incompatible with NT. For this reason any NT-style usage must
be disabled.

This in particular fixes debug assertions and crashes in CRYPT32.DLL (due to
misinterpretation of the structure fields) which happened e.g. during playback of
some Flash content.
