bootstrap gcc for powerpc

[Dimi Shahbaz]

Hi,
I'm trying to create a bootstrap gcc (3.0.4) on i686, target PPC (see 
thread at http://sources.redhat.com/ml/crossgcc/2002-05/msg00093.html ).  
The build fails due to some missing glibc header files.  This appears to 
be the same problem as reported here:
http://gcc.gnu.org/cgi-bin/gnatsweb.pl?cmd=view%20audit-trail&database=gcc&pr=3641

A note there suggests a 'make install_headers' under glibc-2.2.5, 
*before* building the bootstrap gcc.  This works until it reaches:

gcc rpc_main.c -c -O2 -Wall -Winline -Wstrict-prototypes -Wwrite-strings

So the 'install-headers' target wants to run gcc too, for some reason. 
Judging from the cc1 error lines, my guess is that it really wants to 
run the bootstrap gcc, with target=ppc.  Anyone know what I'm doing wrong?

After grappling with this for a week now, I'm thinking of just resorting 
to the following: after building binutils, build a bootstrap gcc using 
gcc 2.95.3 (since that builds OK).  Using that gcc, build glibc.  Once 
glibc is in place, go back and build gcc-3.0.4.  Kind of a drag, but if 
it works, I'll be satisfied.

Thanks
