Hi Simon
and John,

I built successfully uSTL tests using the Simon's latest patch for
arm7tdmi, i386 pc (i386-elf-gcc from eCosCentric) targets.

But, when I tried to build it for i386linux target I got the same error
likes John got.

Simon, I often run update-manager :-( and my stuff is

It seems for me we have to try something is suggested here (for example)
http://lists.busybox.net/pipermail/uclibc-cvs/2005-December/007852.html

Though I did not grep much the NET for the issue...

I will try to investigate in the issue tonight.
