Cool - glad to know it's fixed! If I get the latest gcc sources will it 
be something I can easily build and test out or will that likely get me 
lots of 3.5 changes as well?

I've been using uClibc at work for a client who is building an embedded 
linux system (just built it as part of buildroot, which is an awesome 
package!). That was my first plan of attack, although when poking 
around the web I found various references saying a non-linux build 
wasn't supported - not sure how true that really is. I had started 
trying to build a uclibc toolchain but keep hitting build problems - 
for some reason gcc really hates to compile for me! As you say, uClibc 
is very configurable so it's probably worth spending time on.

As an interim hack, I just tried linking without libc to see how many 
errors I got - turns out it's very little. So I think I will just plug 
in my own functions for now, then once 3.4.2 is out I can go back to 
getting a happy uClibc.

Thanks!
