Hmm..Well I admit that I have not specific experience in the area but
my response was based on a search of the GCC archives for QNX info and
then looking at this FAQ (About a year old)

http://www.schoenbrun.com/mba/faq.htm#L48


It save you having to click it says

48) Is GCC available?

GCC is available, at following URL http://www.teaser.fr/~jcmichot/gcc This
release contain GCC 2.7.2 and G++ compiler. You need WatcomC lib & linker to
use this release of gcc.

In general, once developers start using Watcom C/C++, demand for GCC isn't
as high. Watcom provides a very good, high quality C and C++ development
environment.



So, when I say it is not stable what I mean is it is not in the baseline GCC
tree. It is only supported by
an individual and it requires non GNU libs and linkers...I am not saying
this is impossible to get working
now with GNAT but it certainly is likely to raise the bar.

vxWorks (Tornado) has Ada 95 support from ACT (GNAT), Rational, OC Systems,
Green Hills.
LynxOS has Ada 95 support from ACT, Rational and probably others
Not sure of the state of it but RTLinux from Zentropix was working with ACT
for integration of
GNAT into their RTLinux Product.
There is GNAT support for RTEMS.
Concurrent Computer Corp has what appears to be a nice POSIX compliant RT
Unix based OS
with Ada 95 support fully integrated into their tools.

There are many others. We can certainly debate the "fineness" of these other
RTOSs against QNX but
somewhere in the mix I think you will find an OS that certainly competes.

Having said all of that with QNX being now somewhat free it would be cool if
there was a GNAT
port so since it is just my opionion that it would be difficult to do a port
perhaps you could pull
one together. I'd love to start playing with it on monday. Let me know what
time I can download it.

(Sorry...I am just mean at heart)
