I have a cygwin-based GCC arm cross compiler, more specifically:

http://www.embeddedarm.com/software/software-arm-linux.php
Cygwin Crosstool gcc-3.3.4-glibc-2.3.2

I've set up arm-7800 in user-config.jam like this:
using gcc : 7800 : arm-unknown-linux-gnu-g++ ;

and try to build boost with:
bjam --toolset=gcc-7800 --target-os=linux --threadapi=pthread

All files fail with:

cc1plus: error: invalid option `threads'
cc1plus: error: unrecognized option `-Winvalid-pch'

Is there an option I need to add? or something else...

regards,

Christian
