GNOME and glibc-2.3.4

[Alexandre Hautequest <hquest onda com br>]

Hi folks.

First, sorry if this was discussed before here.

The majority of developers and distro's are using glibc-2.3.3 to write code.
Unfortunately there's others -- i.e those from Slackware -current like myself
-- who upgraded to glibc-2.3.4.

This updated glibc is raising a strange situation in some applications and GNOME
code, specially those network-based: undefined structures, flags and variables
not being correctly inserted.

As could be seen in this small compilation log (cvs from 04.04.2005),

But all these "undeclared" errors are declared in <net/if.h>.

A crappiest example, too:

These same file compiles perfectly when used glibc-2.3.3 include files.

I don't know if GNU folks will accept this issue as a bug for glibc-2.3.4.

While there's only a small part of people using this new glibc version, this is
not a real big issue, but when major distros start to upgrade it, i see this as
a real nightmare.

Any advice?

Thanks.
