Because GCC on AIX is built as a 32-bit executable by default,
(although it can generate 64-bit programs) the GMP and MPFR libraries
required by gfortran must be 32-bit libraries. Building GMP and MPFR
as static archive libraries works better than shared libraries.
Errors involving @code{alloca} when building GCC generally are due
to an incorrect definition of @code{CC} in the Makefile or mixing files
compiled with the native C compiler and GCC@. During the stage1 phase of
