Re: [PATCH] lazyload.h: use an even more generic function pointer than FARPROC

> gcc will helpfully raise a -Wcast-function-type warning when casting
> between functions that might have incompatible return types
> (ex: GetUserNameExW returns bool which is only half the size of the
> return type from FARPROC which is long long), so create a new type that
> could be used as a completely generic function pointer and cast through
> it instead.

> enabled, 2021-09-03), as it will be no longer needed.
