Hi GCC Hackers,
is it possible to build a frv cross-compiler?
I know it is a rather old architecture. But I would like
to try the GDB simulator with Linux and frv, because
there is a working noMMU FDPIC implementation.
I tried different gcc version, gcc 4.8.5, gcc 4.9.3,
gcc 5.2.0 and gcc git. ALl fail with this error:

Is it just a missing include? What is the last known working gcc
version for frv-linux-gcc?
Thanks for any hints,
Waldemar
