With gcc-HEAD as of 2003-06-17, 09:10:00 UTC I get that far:

So it again breaks at a signal include file, but now, it seems to use a correct
one. I've seen this while trying to build other cross compilers (-> for other
architectures), but I never mangaed to really get around that. Googling showed
me that I have to copy target system's header files (libc + (Linux) kernel
./asm-XXX) but I never found a "definitive" guide how to do that and how to tell
this to .../configure ...

Help would be highly appreciated here:)

Hello,

Please in the future include the options you use to configure with when making bootstrap bug 
reports.

Building a cross-compiler is unfortunately probably the worst documented part of gcc. The 
crossgcc mailing list (http://sources.redhat.com/ml/crossgcc ) probably has the most useful and 
current information.

Basically though, you need the headers, and the libraries from the machine you're targetting. Once 
you have those installed in a directory (e.g. /usr/local/alpha-linux/build), you'll need to tell gcc 
where they are with --with-sysroot=/usr/local/alpha-linux/build for configure. Also take a look at 
the cross compiler minihowto (it misses the --with-sysroot but IIRC gets everything else right).

Dara

P.S. If these instructions fix your problem here, I recommend opening a bug essentially stating that 
gcc is effectively lacking on-site cross compilation documentation.

Hello,

this report is currently awaiting feedback. Have you obtained the proper headers to build the cross 
compiler? Does it work?

This is invalid as you have to use --with-headers and with the glibc/linux kernel headers 
on almost all *-*-linux-gnu.
