... so if -ffast-math is already turned on in pd extended I think it's a fortiori safe to turn it on in vanilla :)

I have to think about thi one a little... nobody could ever test -fastmath for all architectures. The danger I see is that some externals might break. Maybe I should just leve it on during the 0.44 test phase and hope I hear back if it's breaking things :)
The reason for putting it in is that I stil get situations where Pd grinds to a halt handling underflow interrupts - it's now a problem on the Pi.

IIRC, it optimizes with the assumption that everything is finite and not NaN, among other things.
I know when I wrote 'tilde' (compiler from Pd dsp to C++), which incidentally used 'double' all the way through, I couldn't always use -ffast-math because it broke some patches very audibly. I didn't have time to debug the issue, so I just removed the flag globally.
