A while ago I posted a call for help (only to autoconf@) taking inventories
of which C headers are provided by which OSes. It rapidly became clear
that my methodology was far too crude, and I've spent much of the past six
weeks coding up something much more sophisticated. The project is now at
the point where I feel comfortable sharing it with a wider audience.
Please see http://hacks.owlfolio.org/header-survey/ for the results so far,
and https://github.com/zackw/header-survey/ for code, raw data, and
instructions for contributing inventories for OSes not yet in the big
table. (Big table only known to work properly in Firefox, say sorry -
patches for the bad stylin' in Webkit most welcome. I've exhausted my
ability to sling CSS.)
If you sent me an inventory already but your OS is not in the big table, I
need you to send it again using the current `scansys.py`. To those of you
who told me that it didn't work with your version of Python, take heart -
it is now tested to work with 2.0. Yes, 2.0.
And you'll find attached QNX 6.5.0 SP1 GCC 4.4.2.
Note, the mknod API of QNX is different to Linux, where most tools I
compile don't work. And when I compiled PHP for QNX, atomic.h is there,
but it's not compatible with Solaris requiring some updates (as PHP assumed)
I see you've got MINGW 2012, but there are two projects, mingw and
mingw64 which are separate and handled separately. Is there a difference
between the two?
I tried to do something similar, and came up with my own list. Does it
make sense to incorporate some of the differences? I was trying to
compile software that works on various OSes for network related
functionality.
In addition, compiler options are important. Many features were only
available for me on Solaris when i compiled with -lxnet on Solaris. See
the html file attached.

jason.

Configuration
Configuration is the basic format and type of information we obtain for
a particular operating system. This information is useful for a
configure script to be able to determine the type of platform it is.
This information is by no means complete and only goes to show some
real world examples. You should research the platforms you are
interested in and investigate the variants you may need to detect. From
autotools, the "config.guess" and "config.sub" scripts will be extended
as new systems are added and these scripts should be used as the
authorative source.

Sockets
Sockets were first implemented by BSD. The sockets interface is
probably one of the most varied interface as each vendor has added
their own extra features, or not implemented features.

Strings
Strings are a common point of failure for security issues (buffer
overflows). The GNU system has extended functions that are similar to
the standard C library. However, not all Operating Systems have
implemented all functions and it may be necessary that local
implementations be written.

Terminal
Terminals are devices that can be the serial port, or the console. In
the early days of unix, they were historically the same (a Wyse
terminal was a terminal connected to a mainframe via a serial console)
