Re: PATCH: CVS build fails for x86 (SUSE 10.3, gcc 4.2.1) with multiple definition of __memcpy_chk

Hi!

(Fixed the subject - I certainly meant SUSE 10.3, not 9.3)

Hmmm, looks like we get a small bit further now, but:

Last time I saw this, I omitted the architecture, but this time I tried
with "--host=i586-linux-gnu" and alternatively "--build=i586-linux-gnu"
(I'm always confused which one to use), but nothing helped. :-(
