Well, I am trying something more sensible now, I think, but it still
is not finding the header files.  I specified the following to
configure: 

/away/zen/gnu/cross/egcs-1.0.1/configure --prefix=/away/zen/gnu/cross/targets/m68k-coff --target=m68k-coff --with-newlib --with-headers=/away/zen/gnu/cross/newlib-1.8.0/newlib/libc/include

So I am building with newlib, which makes sense to me.  :-)

But it is still not finding the header files:

/away/zen/gnu/cross/egcs_build/gcc/xgcc -B/away/zen/gnu/cross/egcs_build/gcc/ -c -g -O2 -I. -I/away/zen/gnu/cross/egcs-1.0.1/libiberty/../include  /away/zen/gnu/cross/egcs-1.0.1/libiberty/choose-temp.c
/away/zen/gnu/cross/egcs-1.0.1/libiberty/choose-temp.c:26: sys/types.h: No such file or directory
/away/zen/gnu/cross/egcs-1.0.1/libiberty/choose-temp.c:27: sys/file.h: No such file or directory
/away/zen/gnu/cross/egcs-1.0.1/libiberty/choose-temp.c:36: stdio.h: No such file or directory
make[2]: *** [choose-temp.o] Error 1
make[2]: Leaving directory `/away/zen/gnu/cross/egcs_build/m68k-coff/libiberty'
make[1]: *** [all-target-libiberty] Error 2
make[1]: Leaving directory `/away/zen/gnu/cross/egcs_build'
make: *** [cross] Error 2

It seems like the problem is in libiberty not finding the include
files.  In fact, grepping the output from the entire "configure .. make 
cross" procedure, I never find any occurrance of the string
"/newlib/libc/include" anywhere except on the "configure" invocation,
which seems like either I am doind something terribly wrong, or
configure does not recognize "--with-headers=" properly.

Is there maybe an undocumented ordering dependency for --with-headers= 
and --with-newlib?
