-pthread support

[Maggie]

Hi all,

I try to generate cross-compiler to support -pthread in command line 
with gcc-4.1.1. I build my compiler using the following configuration.

./configure --enable-threads=posix --target=our-cpu

After I generate cc1, it doesn't support -pthread command, could anyone 
give me some advice?

Thanks in advances

Best regards

Maggie
