Re: gcc+gcj build-times?

[Norman Hendrich <hendrich at informatik dot uni-hamburg dot de>]

Hello Andrew, hello David,

thanks for your quick answers. Until today, I never considered my
machine "memory limited", but things do change... Obviously, I ran
into a combination of problems - slow compiler (gcc 4.0.0), too old
gmake, too small memory, and full bootstrap mode).

When (if) I next build gcc, I will try the --disable-bootstrap option.

Well, my motivation to rerun the three-hour bootstrap is pretty low
right now ;-)  Rerunning "make install" grinds to a near-halt at this
point:
