Yup... it looks half ported; right up through ctype.h it looks like the
author had reduced the headers to what was available, and then surrendered.

I suspect that this is the typical kitchen sink; throw in every usual
header so that any feature is available.  It might be worthwhile to comment
them all out and readd them one-by-one for the actual declarations that are
required by the code.

Witness, for example, the redundant sys/types.h :)

As I mention, comment them all out (I prefer #if 0 ... #endif for that sort
of thing) and start readding one-by-one, and possibly even state something
like /* for foo_fn() declaration */ explaining why that header is needed.
