Bug#351629: Recent libc6-dev broke compatibility with sarge binutils and gcc-3.3

["Nikita V. Youshchenko" <yoush@debian.org>]

Package: libc6-dev
Version: 2.3.5-12.1
Severity: important

After upgrade libc6 to 2.3.5-12.1 our locat projects failed to build.

Minimal test that reproduces the problem:

nikita@zigzag:~/adm/libc> cat t.c
#include <stdlib.h>

void at() {}

int f(void)
{
	atexit(&at);
	return 0;
}

nikita@zigzag:~/adm/libc> gcc -shared -o libt.so t.c
/usr/lib/libc_nonshared.a(atexit.oS)(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x0):
In function `__i686.get_pc_thunk.bx':
: multiple definition of `__i686.get_pc_thunk.bx'
/usr/lib/gcc-lib/i486-linux/3.3.5/crtbeginS.o(.gnu.linkonce.t.__i686.get_pc_thunk.bx+0x0):
first defined here
collect2: ld returned 1 exit status

Error goes away if libc is downgraded to version in testing.
Error was not there before today's upgrade (so it not was there in
2.3.5-12 version).

Error also goes away if binutils is upgraded from sarge version to version
currently in unstable. But this upgrade in turn causes problems with
usage of g++ 3.3, described at
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=16625. This problem happens
on Debian if binutils are post-sarge, with any version of g++-3.3
packages.

So at least, dependency on recent binutils should be added.

But it would be much better if compatibility with sarge binutils will be
preserved in libc6-dev until a workable combination of g++-3.3 and
post-sarge binutils will be found. Unfortunately, we do have to use
g++-3.3 ABI here, and I'm sure we are not alone with that.
