Comment (by jflude):

 There are two apparent issues with this port.

 1. The `master_sites` now points to a dead link, so the source code cannot
 be downloaded.  This is easily fixed by pointing to the new master site.

 2. The code is old and does not declare function prototypes, which leads
 to a number of warnings from Apple's latest compiler for some function
 calls, which can be ignored, and one error, which cannot (for `xpopup` in
 `encoder.c`).  This is easily fixed by declaring a prototype.

 I will update the patches and raise a PR in the next day or two.
