Subject: [PATCH] Sync to wine-1.1.1 (Patch 4 of 10):

ATTENTION: You MUST run "clean" before building ReactOS, otherwise WIDL will crash when it is run.

- Dan Hipschman <dsh@linux.ucla.edu> Tue, 1 Jul 2008
widl: Implement type redefinition checks.

This allows widl to catch type redefinitions and report an error, like MIDL.
However, this does a better job than MIDL since it also reports the location
of the originial definition, like GCC.
