msvcrt switching from builtin to native

[Uwe Bonnes]

Hallo,

trying to run msdev.exe with builtin msvcrt, at some point thins strange
+snoop,+relay log appears:

08066950:Call msvcrt._strdup(4040b294 "Microsoft Visual C++") ret=5f416652
08066950:Call kernel32.HeapAlloc(40390000,00000000,00000015) ret=4063d846
08066950:Ret  kernel32.HeapAlloc() retval=4041c338 ret=4063d846
08066950:Ret  msvcrt._strdup() retval=4041c338 ret=5f416652
08066950:Call msvcrt._mbsinc(5f49d450 "%d") ret=5f4160fb
08066950:Ret  msvcrt._mbsinc() retval=5f49d451 ret=5f4160fb
08066950:Call msvcrt.atoi(5f49d451 "d") ret=5f41614d
08066950:Ret  msvcrt.atoi() retval=00000000 ret=5f41614d
08066950:CALL msvcrt.292: _ismbcdigit(<unknown, check return>) ret=5f416161
         ^^^^
08066950:Call ntdll.RtlRaiseException(406064e0) ret=40631056
08066950:CALL msvcrt.74: __CxxFrameHandler(<unknown, check return>) ret=4006ac97
08066950:Call ntdll.RtlRaiseException(406061d0) ret=40631056
08066950:CALL msvcrt.74: __CxxFrameHandler(<unknown, check return>) ret=4006ac97

_ismbcdigit is unimplemented. The log looks like wine starts to think with
that call that msvcrt is a native dll. Implementing a semi stub for that
gives the same behaviour at the next unimplemented msvcrt function.

Bye

I was just noticing similar situations with urlmon when i we debugging
something today. I thought there must be something wrong with my setup,
but if you are seeing it also that is interesting.
