Is your feature request related to a problem? Please describe.
I found a nice feature called "Parse C Source" and tried it with my MSVC 2022 headers. I copied VisualStudio22_64.prf to a new profile, modified the profile's included paths to the paths on my machine and ran it. It failed with an error indicating that it can't parse an enumeration in C:\Program Files (x86)\Windows Kits\10\Include\10.0.26100.0\um\ProofOfPossessionCookieInfo.h:

typedef enum _PROOF_OF_POSSESSION_FLAGS : DWORD
{
    PROOF_OF_POSSESSION_DEFAULT                      = 0x0000000000000000,
    PROOF_OF_POSSESSION_ALLOW_SILENT_REQUESTS        = 0x0000000000000001,
} PROOF_OF_POSSESSION_FLAGS;

After troubleshooting I found that the : DWORD is a feature called "Explicit Underlying Type" supported by MSVC C++ compiler:
https://learn.microsoft.com/en-us/cpp/dotnet/how-to-define-and-consume-enums-in-cpp-cli?view=msvc-170

I tried to create a C source file with the syntax above, compiled it and MSVC C compiler complained that it doesn't support this syntax.

Describe the solution you'd like
I have read the document and found that Ghidra doesn't support C++ header files. I think there're two ways to improve the user experience:

1. Comment out ProofOfPossessionCookieInfo.h.
2. Add support of this syntax.
