/* On Windows, some functions use the `stdcall' calling convention,
in which the callee is expected to pop the arguments off the
stack. Normally, the caller takes care of this, because only the
caller knows how many arguments it really passed. To avoid
confusion, the linker symbols for `stdcall' functions have names
with a suffix "@N" attached to them, where "N" is the number of
bytes they'll pop. That way, if a caller thinks some `stdcall'
function `foo' expects M argument bytes, but the definition of
`foo' expects N argument bytes, N != M, then the call will be a
reference to `foo@M', but the definition will have a linker
symbol `foo@N', and you'll get a link-time `symbol not found'
error, instead of a crash at run-time.
(Note how this fails to address calls through function pointers,
since the byte count isn't part of the function pointer's type.
Go, Microsoft!)
Whatever. But our demangler doesn't like that '@N' suffix, so we
need to strip it off. */
