_thiscall Calling Convention as Specfile option or via register
Hallo, as Jason noticed, in MSVCRT there is a _thiscall calling convention that uses the ECX register for the 'this' pointer. Should we have another Specfile keyword in our spec files or should the _thiscall calling convention be implemented via the 'register" keyword?

I don't think it can be done in the spec file, since this would break the mingw build. If there are many of them we could create inline asm macros to make them easier to use than with full-blown register functions. Do we have a list of the offending functions? -- Alexandre Julliard julliard(a)winehq.com
