Those patches fix powerpc target build.
Both are attached.
I've sent them to gcc maintainer; one for gcc-3.3 was applied to official
gcc-3.3 3.3.4-1 package (so it is not needed if you use that or later
version).
I'm thinking of enabling/fixing cross-compiler builds also for gcc-2.95 and
gcc-snapshot packages. What do you think of those?

I've uploaded some binary debs to my repository
(http://zigzag.lvk.cs.msu.su/~nikita/debian); they are apt-gettable from
there now.
But emdebian server is probably a better place.

I don't know what targets are really needed for embedded developers, but I
see no harm if all targets that build ok will be available.
Nikita
P.S.
What to do with dpkg-cross? Sid STILL has broken 1.14 ...
Well, there still are some items in my TODO with it:
- - make README.Debain up-to-date: this 33k text document has tons of
obsolete information, so I feel I should do a massive rewrite :(
- - make it support 64bit targets - should be trivial, but I first should
find out exact requirements
- - make it possible not only to define vars in /etc/dpkg/cross-compile, but
also to undefine those defined by default. There is a wishlist bug on
that; first I wrote there that I see no rationale for that, but after I
became more familiar with dpkg-cross, I tend to agree with bug's submitter
- - (probably) add apt-get wrapper for installation updates
- - (probably) look how it works with hurd target(s)
But none of those is important enough to delay upload.
