Some problems with wine on linux

[itziakos]

It looks that there are incompatibilities with the wine implementations of

• EnumResourceTypesW -- When there are no resource types to enumerate the function instead of True will return False (see https://github.com/wine-mirror/wine/blob/master/dlls/kernel32/resource.c#L250)
• BeginUpdateResourceW -- will return a Null handle if the filename is invalid but will not set a proper errorno (https://github.com/wine-mirror/wine/blob/master/dlls/kernel32/resource.c#L1655))
• EndUpdateResourceW -- will return False if the handle is invalid but will not set a proper errorno(https://github.com/wine-mirror/wine/blob/master/dlls/kernel32/resource.c#L1715)

It's worth reporting these to wine bugzilla https://bugs.winehq.org/ there's an even chance someone will turn up to fix it.

Let me know if your happy for me to upstream these to wine, it looks like there is enough info for them to fix these? Though my win32 knowledge is pretty lacking.

Sure, feel free to report the issues. The primary target platform for pywin32-ctypes is windows so, supporting wine is not at the moment high up in the priorities. Testing on wine was an early necessity (and kind of a cool thing to do) so that we could have automatic testing using travis-ci. Switching to appveyor made it unnecessary, so I removed it.
