  Most people have troubles the first time they learn how to make a 
cross compiler.  Once you've done it once, it gets easier!

  The CrossGCC FAQ, although it is good in many ways, is sadly out-of-
date.  In particular, it doesn't mention the need for target headers.  It
is also just plain wrong about the build process when using newlib.

  Hmm.  I think this may be related to the fact that the Cross GCC FAQ
says you must build and install gcc before newlib.  That might have worked
back in 2.8.1 days, but not any more.  What you have to do is

 - configure gcc using the "--enable-languages=c" option

 - "make LANGUAGES=c all install" for gcc.  This installs the c compiler 
only, but as long as you followed the advice in my previous email of
16/Mar/01, 16:30 GMT, it should also install the newlib headers

 - now configure newlib, and do "make all install" for it.

 - now re-configure Gcc, but with "--enable-languages=c,c++" (or with no
enable-langs option at all if you want the fortran, chill, java compilers
to also be built).
 
 - finally "make all install" for gcc once more.
