Building gcc-3.0 cross sompiler

[Paul Flinders <P dot Flinders at ftel dot co dot uk>]

I'm having difficulty building gcc-3.0 as a cross compiler
hosted on RedHat (6.2 or 7.0) and targeted at linux-ppc

I've compiled binutils OK and installed into the target
tree. Then building gcc fails as it tries to build libgcc2
with the following error

/u/ptf/gcc-3.0/gcc/xgcc -B/u/ptf/gcc-3.0/gcc/
-B/opt/gcc-ppc/powerpc-linux/bin/ -B/opt/gcc-ppc/powerpc-linux/lib/
-isystem /opt/gcc-ppc/powerpc-linux/include -O2  -DCROSS_COMPILE
-DIN_GCC    -W -Wall -Wwrite-strings -Wstrict-prototypes

libgcc/./_muldi3.o

                 from config/rs6000/xm-sysv4.h:35,
                 from tconfig.h:3,
                 from libgcc2.c:36:
config/rs6000/linux.h:81:20: signal.h: No such file or directory
config/rs6000/linux.h:82:26: sys/ucontext.h: No such file or directory
make[2]: *** [libgcc/./_muldi3.o] Error 1
make[2]: Leaving directory `/u/ptf/gcc-3.0/gcc'
make[1]: *** [stmp-multilib] Error 2
make[1]: Leaving directory `/u/ptf/gcc-3.0/gcc'
make: *** [all-gcc] Error 2

It looks as though it wants signal.h and sys/ucontext.h from the C
library.
Obviously they aren't there because I can't build the cross C library
until
I've built the compiler.

Am I doing something wrong?
