[svlug] libc questions

[Michael K Vance]

Hello,

First, I'm going through the glibc build process right now. Lots and lots of
it builds properly, but then I get this:

[mvance at localhost glibc-2.0.103]$ make

[...]

make  -C db2 others
make[1]: Entering directory `/home/mvance/glibc-2.0.103/db2'

[mvance at localhost glibc-2.0.103]$ 

Additionally, how dangerous is it to remove the RedHat v5.0 libc5
compatability libraries from my machine? I haven't installed anything that
requires them, so I guess I'm interested in what the baseline installation
requires of it. A simple 'rpm -q --whatrequires libc' didn't turn anything up
(though it never seems to...).

Thanks,

m.
