OK.  I just don't know how real Kir's fears are.

While I don't strongly state anything, why?  AFAICS in changelogs, gcc
4.4.x has all significant features we want to use (like SSP), 4.6.x has
probably not too much important for us improved C++1X support, more
strict compile time checks, better standards conformance, and many
changes in Ada, Go, Fortran, etc.; support of new -mXXX, non-x86 archs
support/improvements, etc.

I'll try to make 2.6.18 kernel compilable with gcc 4.6.1.
