PATCH: makepath - do not use stack buffer

[Marcus Meissner]

Hi,

Do not use a temporary buffer in _makepath(), we can just operate
on the target buffer.

(This avoids overflowing tmpPath, which was just 256 byte large.)

This is the same as _wmakepath() does.

Ciao, Marcus

Changelog:
	_makepath(): operate on targetbuffer directly.
