[ECOS] Howto get basic STL running

I've applied the patch(there was a small bump in the road, since my
patch command didn't grok the patch format, fixed patch attached), but I
run into problems with include files which I don't understand.

>From my toolchain:

./ecos/gnutools/arm-elf/arm-elf/include/bits/functexcept.h
./ecos/gnutools/arm-elf/arm-elf/include/exception
./ecos/gnutools/arm-elf/arm-elf/include/exception_defines.h
./ecos/gnutools/arm-elf/arm-elf/include/stdexcept

Here is the error messsage:
