stl implementations--does anybody use SGI STL anymore?

[Randy Smith]

I am curious what the dominant stl implementations available are nowadays.

I've used the SGI stl implementation for quite a while alongside gcc, 
but a recent upgrade to gcc (using 3.4.4 now) will not compile the sgi 
stl, and it looks like non-standards-compliant code is the culprit. 
Browsing around using google, I could find very little information on 
sgi stl, so I'm guessing it has gone into disuse.

Although it has been several years since, I have experienced some pretty 
nasty multi-thread-triggered bugs in the gnu stl that were not 
problematic in the sgi stl (the bug had to do with inherent 
thread-safety problems in gnu stl's implementation of string creation).

So, I guess I'm curious if anybody still uses the SGI STL and if there 
are issues in getting it to compile with late versions of gcc.  If not, 
is gnu stl considered production quality?  what else do people use?

thanks,
