I think we need to be (much) more careful about the ever increasing
amount of dependencies needed for GCC, especially when it's something
benefiting only a small minority of our user base like compex math.
Even more so when the new dependency is immature and very much in flux.
As an example, half a year ago one could not longer even build mainline
GCC on a GNU/Linux distribution that was only a year old back then due
updated version requirments on MPRF.

Not for GCC 4.5, please. Pretty, please.
