gcc4.1.2通过rpm包升级gcc4.4.7

由于环境不能连外网，不能通过yum安装，所以我采用rpm包安装的方式。
所用系统为CentOS 6.3,64位。

所需安装包
gcc-4.47-17.e16.x86_64.rpm
cloog-ppl-0.15.7-1.2.el6.x86_64.rpm
mpfr-2.4.1-6.e16.x86_64.rpm
ppl-0.10.2-11.el6.x86_64.rpm
cpp-4.4.7-17.el6.x86_64.rpm
libgcc-4.4.7-17.el6.x86_64.rpm
libgomp-4.4.7-17.el6.x86_64.rpm
