* alloca: somewhere later in the code, we indirectly include alloca.h
which will define alloca again, include it prior to define alloca in
order to not define it against.
* Copy all attributes from the header to source file, and move the
attributes prior to function name. cgcc is very picky on the position
of attribute.
