iobuf_alloc := _posix_memalign

ProDOS 8 requires an page-aligned 1kB IO-buffer for every open file. The implementation using posix_memalign() is universally correct but quite expensive. There I added support for overriding this implementation with maybe limited (i.e. to one open file) but cheaper custom implementations. git-svn-id: svn://svn.cc65.org/cc65/trunk@4142 b7a2c559-68d2-44c3-8de9-860c34a00d81 2009-09-10 09:59:26 +00:00			`;`
