Seeing "@@GLIBC_2.0" in libraries: how come?

[Andrew Morton <andrewm uow edu au>]

Not a gtk problem, I know, but could someone please explain to me why
the gtk+-1.1.13-1 rpm which I just pulled from
ftp://rpmfind.net/linux/rawhide/1.0/i386/RedHat/RPMS/gtk+-1.1.13-1.i386.rpm
has "@@GLIBC_2.0" appended to all its references into libc?  I haven't
seen this before.


/usr/lib> nm libgtk-1.1.so.13.0.0 | grep GLIBC
         U ___brk_addr@@GLIBC_2.0
         U __bzero@@GLIBC_2.0
         U __ctype_b@@GLIBC_2.0
         ...


Thanks,
Andrew.
