If I read the question correctly, the Apache Portable Runtime (APR) comes 
pretty close to a portable OS abstraction layer, and offers file/directory 
access, mutex primitives, TCP/IP sockets abstraction, and various other 
facilities ... Its license is permissive (not GPL), and it is in daily use 
on millions of platforms support for Unix, Linux, Windoze and others ...

Not attempting to start a language battle but Ada is available for all 
of those platforms and can provide the functions you are looking for.

Supported.

Also there is Microsoft Interix - a free download from MS IIRC, which is =
the same as Cygwin and probably better.

I assume you've considered Cygwin?
www.cygwin.com
It provides a Linux abstraction on Windows. Not sure if Vista is 
supported, but we use it on XP Pro.

I would recommend looking into ACE. ACE has a built in hardware
abstraction layer that should be useful.

 abandoned?

  OSAL had a release in Oct 2007. The whole idea of open source is
that others contribute to make it better.
  If you or your company can't contribute, then it is best to purchase
a commercial product.

Then Ada would suit just fine -- we regularly port the same code base
between Windows, Linux, Solaris, Mac OS X, VxWorks.

All these can be had for free (with a bit of digging) bar VxWorks. A
powerpc-wrs-vxworks compiler and support for GCC GNAT Ada is available
at a cost which makes more sense if there are several of you and you
need support. People like Green Hills, Aonix support VxWorks for fewer
bucks. I believe a free GNAT is available for MaRTE OS,

Why would you expect that ?

Take a look of some OS independent API, try to port it to all your
required operating systems using their native primitives. 

If there are features that do not _readily_ map into _all_ OS
platforms, just advice application programmers that these features
should not be used if possible.

I thought it was probably embedded, and possibly real-time, given the 
newsgroups you posted to, but then you mentioned windows!  Embedded 
systems are often connected to PC's to provide a non-critical gui, so it 
was worth checking.

 From what I've read from your other posts, it does sound like posix may 
be your best bet.  Since posix is a standard, and everyone likes to 
implement different bits of standards in different ways, you'll have to 
find a common subset that is reasonably consistent across your OS's, but 
it could be a workable starting point.

Sorry, I should ahve said - it's embedded stuff. So, no gui, just
message send/receive, task spawn/kill, timers, mutex, semepahore...
