Tom,

Yeah, I've already fired off a query about this gcc build to the source.

In my case, I downloaded it from www.sunfreeware.com, and, for good measure,
I also tried gcc 3.4.2 for solaris 9, on a solaris 10 box, and, indeed, it
looks like the same problem is there.

So, it's entirely possible that the build they've got listed for 10 was
either built on a version of solaris 10 which was earlier than what I'm
using (b69), or, it could have been built on a solaris 9 box.

Either way, I'm asking about it, because it does seem, to me, to be a gcc
problem.

I could try building gcc myself, but, that won't fix the problem with the
version on the sunfreeware site, which a lot of people rely on, I expect.

Regards,
Peter.

On rereading this, a nearly-dead neuron fired --- I have seen problems of
this sort arise when someone took a gcc installation generated on
NiftyVendorUnix M.N and copied it verbatim to NiftyVendorUnix M.N+1, or
indeed any release other than M.N.  Then you have a situation where gcc is
inserting cleaned-up versions of some system headers but not others (because
it doesn't force the issue when it doesn't have to), and if the vendor did
something like move a typedef from one header to another, you lose, because
the cleaned-up headers are not in sync with the others.

In short ... where'd you get your gcc installation from?
