It was much easier to find dependences than I thought. Required items to
build GCC 4.6.2 are described in GCC documentation :-)

 gcc-4.6.2/INSTALL/prerequisites.html

It seems to me GCC build requires GMP, MPFR, MPC libraries (Necessary to
Build GCC). So, these libraries look like SHOULD requirements.  And PPL,
CLooG (IMHO) look like COULD requirements (Necessary to build GCC with
the Graphite loop optimizations), and may be even WON'T requirement for
eCos.
