Package: gcc-4.6
Version: 4.6.2-6
Some large number of packages (I'd guess around 700 +/- 200 source packages)
generates on armel and armhf the warning:
dpkg-shlibdeps: warning: symbol __aeabi_unwind_cpp_pr1@GCC_3.5 used [...] found
in none of the libraries.
(or some variant).
While is ome cases it could be a missing libgcc there are some other
examples:
First case (libtool, with -nostdlib and -lgcc_s):

With only -shared and no -nostdlib or the like, it should be gcc's
responsibility to link the needed system libs, shouldn't it?

Is this a bug in gcc/libgcc or something else (libc?, ld?).
Or should dpkg-shlibs just ignore this particular symbol?
Thanks in advance,
