RtlEnterCriticalSection

[Michael Marxmeier]

After encountering timeout messages from
RtlEnterCriticalSection i had a look at it.

Since interlocked_inc() should never return zero
the following patch is likely necessary.
I was unable to test this as now wine crashes with
a segmentation fault (which also terminates gdb).
