Bug 24071 – When enum has typedef integer constants do not have types determined correctly

From wingdi.h: ```c typedef enum { DISPLAYCONFIG_OUTPUT_TECHNOLOGY_SVIDEO = 1, DISPLAYCONFIG_OUTPUT_TECHNOLOGY_INTERNAL = 0x80000000, } DISPLAYCONFIG_VIDEO_OUTPUT_TECHNOLOGY; ``` Remove typedef and it works. Some of the output: ``` C:\Program Files (x86)\Windows Kits\10\include\10.0.20348.0\um\wingdi.h(2804,61): Error: integer constant expression expected instead of `cast(uint)-1` C:\Program Files (x86)\Windows Kits\10\include\10.0.20348.0\um\wingdi.h(2805,61): Error: integer constant expression expected instead of `cast(uint)0` ```

Is the snippet alone supposed to reproduce it? I don't get the error, and I'm not on Windows so I don't have the entire file.

Created attachment 1884 wingdi.h for 10.0.20348.0 It was enough to produce the error on my machine. Took me quite a while to minify it down to this. I've included my copy of wingdi.h here however in case it is of interest.
