WRT to bootstrap time, as usual: it's too long.
Well, that all depends on your (time) frame of reference, of course. In the summer months leading up to Craig Burley asking for volunteers testing g77 (the g77-alpha phase), i.e., during the summer of 1992, a bootstrap of GCC (C and C++) took 8 hours on my single 25 Mhz Motorola 68040 powered Next Station.
With the new gcc, I could build a fresh f2c in minutes, and, using that combo (f2c+gcc) a recompile of our weather forecasting code took another 10 minutes.
Nowadays, on a *4 year old* quad core Core 2 machine, building C, C++, Ada and Fortran takes less than 2 hours, so given that I put in 4 times as many processors, the rest of the hardware keeps up with providing me a bootstrap in 1/4th of the time it took 19 years ago, giving me twice the number of front ends plus run time libraries.
