compiling gcc 2.95.3 under ubuntu 10.04.2, x86_64

[Roman Suvorov]

Hi Mike,
xz (and liblzma) are definitely installed (v. 4.999.9beta), and I'm using tar 1.22. I looked through all of the configure tool's help, nothing mentions X-CheckUnifiedSystemdir. I'm already enabling just about everything with my configure options (except hackingdocs & selinux, but those are probably not relevant).
Cheers,
Roman.
