GCC 3.4 or higher is required; as of this writing, GCC 4.4 is the

machines including `powerpc64', compilers prior to GCC 4.0 have
bugs that prevent them compiling the C library code. On other
machines, GCC 4.1 is required to build the C library with support
for the correct `long double' type format; these include `powerpc'
(32 bit), `s390' and `s390x'. For other architectures special
compiler-provided headers are needed (like `cpuid.h' on x86) which
only come with later compiler versions.
