It does not compile, so let’s install an older version of gcc.

cd gcc-4.3.3

d’aprs https://gcc.gnu.org/install/prerequisites.html il faut gmp 4.3.2, MPFR Library version 3.1.0 (or later), MPC Library version 0.8.1 (or later)

as I got acos.c:192:19: error: GMP_RNDA undeclared (first use in this function); did you mean GMP_RNDD? I changed MPC release I also had to change mpfr to 3.1.2 instead of 3.1.0 because of compilation problems.
