In modules/system/time, a bad prototype for "time" was left. There is too some problem with filno under OpenBSD. Currently, the only known OS that don't want to export fileno with c89/c99 standard, is linux, so #ifdef/#endif the prototypes only for linux. (OpenBSD seems to define them as MACROs, that led to errors)
The prototypes difference between platform is really annoying, since it's hard to always match the system on, and prevent warning on bad types. I try now to always use BRK emulation on all platform that do not match the prototype used in ACK. the PM script should be changed to set this correctly during setup.
Mac OS X seems to have some difficulties with brk/sbrk (maybe with the
4MB heap limit), and replace all the allocation logic will be prone to
errors, I'll add a new define and lib to emulate brk/sbrk using more
standard allocation methods. By default the heap is 64MB, it should be
enough.
These files "magically reappeared" after the conversion from CVS to
Mercurial. The old CVS repository deleted these files but did not
record *when* it deleted these files. The conversion resurrected these
files because they have no history of deletion. These files were
probably deleted before year 1995. The CVS repository begins to record
deletions around 1995.
These files may still appear in older revisions of this Mercurial
repository, when they should already be deleted. There is no way to fix
this, because the CVS repository provides no dates of deletion.

I already did this in abebf1586c06, but I edited the wrong file. Then
in edddc6b7cd17, I deleted that file.
By fixing fit16i(), I can now compile ACK for OpenBSD/amd64.
