Yus... the statements I've had from Sony on the matter are usually
along those lines, with no further explanation, which is why I thought
I'd ask.

In practice the only real problem you get with C++ on the pro kit is
that the final CD-based startup code forgets to call constructors, and
I both discovered and got around that today. In Yaroze terms, I don't
see the problem. You'd need to add extern "C" to the headers (in fact
its absence makes me wonder which version of the libraries was used
for Yaroze ;=). The Yaroze linker script already handles global
constructor collation; all you'd need is the right bit of startup
code, which should be somewhere in the GCC source already, and you're
away. The wording of that last Sony sentence is what's always confused
me; you don't *need* any support in the PlayStation-specific
libraries, support files, and C include files for C++ to work. Whether
it does a full ANSI C++ job is another thing, but it's not like
PlayStation C is ANSI-compliant. The GNU libg++ library could
conceivably be ported, but SN hasn't had the time yet, and no-one else
wants to spend the time and money on doing it - although I don't doubt
everyone would snap it up were we to do it :)
