Re: [gpsd-dev] Windows version of libgps

[Robert Norris]

Although Windows doesn't have unistd.h, the MingW system provides a minimal 
version but lacks a fork() function - so it doesn't build for me.

Thus it would be better if the os_daemon() versions are decided by a #ifdef 
HAVE_FORK instead.

This then builds on my set up and I've made a couple of changes to gpxlogger.c 
to enable this to build on Windows (mostly disabling calls to syslog()).

I've yet to test it running but should be a useful utility on Windows (although 
of course it will lack a daemonize option).

I merged those two patches, though I have a followup patch related to
os_daemon(), which does two things:

1) It provides a dummy always-failing version, rather than simply omitting
the function, in order to maintain API consistency.

2) It bases it on "not Unix" (specifically, the absence of unistd.h)
rather than the presence of Winsock.

I don't have a way to test this on Windows, so I haven't pushed it to
master yet, but it's available on my GitHub windows-fixes branch:

Could you (Robert) test this on Windows?

As things presently stand, cross-OS cross-building doesn't work for
multiple reasons.
