Why are stdcall and regparam not allowed together any more? They seem
entirely orthogonal to me, and the overall result is effectively to place an
arbitrary limit of 1 (the hidden this pointer) on the number of parameters
that can be passed in registers.
If I change __stdcall to __thiscall in the example, I get a clear error
message:

However in the original case the error message about "ambiguates old
declaration" is unclear: a) it doesn't say what the problem is, b) it goes
away if you repeat the regparm attribute on the function definition and
appears to compile correctly, generating what looks like valid assembly to me.
