GNU g++ is probably the only compiler available on all those platforms,
and its free. Therefore if you stick to g++ on all the platforms, you have
a much beeter chance of porting your software with minimal system
dependancies.

: Nope.

g++'s templates are reasonable, but exceptions have only just been added
and are not stable. Unfortunately the way g++ does templates is very
different from cfront, so it is difficult to cleanly port between these two
compilers.

Hello,

I want to develop a product in C++ in many UNIX platforms(SunOS,HP-UX,
Solaris, AIX, NCR, Pyramid, ...)

1) Is there a C++ standard that I may rely on?
2) Is there a compiler which supports this standard across
   multiple Unix platforms?
3) Can I assume that features like templates and exception handling
work under all platforms?

Please answer by E-mail.

Thanks

Nope.  (There are some compilers that work for multiple platforms, but
singe there is no standard yet, none of them fully support the as-yet
non-existant standard.  None of them even fully support the current
*draft* of the standard, despite all marketing claims to the contrary.)

Nope.
