The following was produced on a gentoo x86 linux system with a pentium-m
processor, the system compiler is Gentoo 4.3.3-r2 and kernel is
linux-2.6.28-gentoo-r5.
Last night, I built gcc 4.4.0 and installed it into /home/bgalehouse/installs.
I then reconfigured a library (CGAL) to make use of c++0x features, and tried
to compile a program. This program worked fine under the system compiler when
the library is configured to avoid c++0x features. I might have time to compile
and try a recent snapshot over the next few days, if so I'll try to amend this
bug report accordingly.
