compiling gcc 3.4 on linux, debian unstable

[Ken Foskey]

When I compile from head I get the following error:


make[2]: Entering directory `/data/gcc/i686-pc-linux-gnu/boehm-gc'

Is there a tag that will give me a reasonably reliable build for gcc 3.4
but still keep me ahead of the game.  I want to ensure that
OpenOffice.org is buildable in releases of gcc as soon as they are
released not after weeks of pain.
