If mpfr and gmp are included in gcc, every update (or only security
update?) of mpfr or gmp should be followed by re-casting of all gcc.
For example mpfr's HISTORY:

2009-02-26 Ladislav Hagara <hgr at vabo.cz>
        * DETAILS: 2.4.1, SECURITY_PATCH=1, buffer overflow

This would certainly causes re-casting of gcc  (3 hours....).
Mpfr alone last only 1 or 2 minutes.

# ldd /usr/libexec/gcc/i686-pc-linux-gnu/4.3.3/cc1
        linux-gate.so.1 =>  (0xffffe000)
        libmpfr.so.1 => /usr/lib/libmpfr.so.1 (0xb7fde000)
        libgmp.so.3 => /lib/libgmp.so.3 (0xb7f8a000)
        libc.so.6 => /lib/libc.so.6 (0xb7e49000)
        /lib/ld-linux.so.2 (0xb805a000)
