Well it depends.  One of the authors, has his whole machine compiled with
pgcc, kernel,x,all /usr/bin..., so it seems stable.  However, it seems to
have gotten a few of gcc-2.8.0's bugs, and it didn't compile all c++
programs I threw at it.  This really isn't it's fault since it's pretty
much known that 1)a new libg++ is needed, and 2)g++ is broken. 

On the speed front, it really depends according to them.  They say the
speed increase can be anywhere from 5-30%.  Their hand tweaked version of
gzip, is about 35% faster.
