 libchk port could help, too. But it seems top be broken. It shows,
 that system /usr/lib/libstdc++.so.6 depends on gcc44's libgcc_s.so
 and it is completely wrong!

 I'll fill pr about it!

  Yep, but it is very long way when you have, say, kde4 installed. It
 is why I want to determine MINIMAL set of ports, which are REALLY
 depend on gcc4

  For example, x264 DEPENDS on gcc, (has USE_GCC=4.4+ in Makefile),
 but no x264 files are linked with libgcc_s.so or other libraries from
 gcc44. It seems, that we need separate USE_GCC_BUILD and USE_GCC_RUN,
 as with PERL or PYTHON.
