Without checking: It probably has this only if __STDC__ is not
defined. MSVC hides all non-standard symbols if __STDC__ is defined -
either by compiler switches, or in some application header.

In that sense, _alloca is the Microsoft name for this extension. They
may have been misguided by using that scheme, though, since _alloca
isn't any more reserved than alloca.

However, all uses of _alloca in posixmodule.c are MS specific, so I
really see no reason to change that.
