gcc-4.0.0 for sparc-sun-solaris2.8: Almost all good!

[Brad Spencer <spencer at infointeractive dot com>]

First, let me say sorry for not being able to test properly before the
release of gcc-4.0.0.  Constraints here made it impossible :(

However, I have had no trouble building sparc-sun-solaris2.8 gcc-4.0.0.
I build a cross, hosted on i686-pc-linux-gnu, and I build a Canadian
cross (how appropriate ;) using that, which I then run on Solaris,
targeting Solaris, when necessary.  All of this went more smoothly
than anything in recent memory.

I have spent some time over the last few days exercising the cross
compiler with large chunks of our source and haven't run into many
snags.

Speed-wise, if anything, the new compiler seems a bit faster.  Some
timing results for a small subset with some heavy template usage.
These were using the Linux-hosted cross compiler:

gcc-3.4.3:

real    5m30.053s
user    6m26.404s
sys     0m29.438s

gcc-4.0.0:

real    5m24.522s
user    6m15.444s
sys     0m25.392s

There's only one real problem that I've found so far.  I'm hoping
someone can point me in the right direction and I'll investigate more
and file a PR. 

One library I have makes heavy use of Boost.Spirit, which is heavy on
templates.  Strangely enough, though, when I link this static library
against code that uses it, ld 2.15 claims that some of
std::vector<std::string>'s member functions are not available to
link.  It takes a very long time to conclude this, as if it is
searching through every symbol (linearly?).  I've attached some sample
output and more details on the compilation.

I fixed this by adding the following to the library:

  template class std::vector<std::string>;

Clearly, I shouldn't have to do that.  In my mind this could be
libstdc++ or gcc.  Ideas?  Narrowing this down to a simple test case
is very difficult; this is only happening in the complex case of using
Boost.Spirit. :(

Other than that, everything seems to be working fine, including wide
character support after Benjamin's rewritten configury.
