> It's using -lz within the build, so I believe all uses are of the static
library.
OK.
> Any time that can be saved is worth considering saving. In any case, the
version of zlib that comes with gcc is an older one and for some reason it
takes much longer than 5 seconds. Run through a build, you'll see what I
mean.
Define 'much longer'. I'd still be nervous about it.
> Zlib already is before GCC in chapter 6.
Yes. For some reason I was thinking of glibc.
> > I don't see other distros doing this and the potential to do harm is
greater than what appears to be a negligible benefit.
> I would accept this as a potentially valid argument if you applied that
same principle to the other libraries that gcc uses and could be built in
statically, namely, gmp and mpfr. As it is, since you install those to the
system in chapter 6 solely for the sake of GCC, then you're already
setting a precedent.
We build gmp and mpfr separately so other programs have them available. I
have no idea why gcc needs libz anyway. It doesn't make sense to me.
