Downgrade GCC from 4.6 to 4.4

You could install both 4.6 and 4.4 version

$sudo apt-get install gcc-4.6
$sudo apt-get install gcc-4.4
$sudo apt-get install gcc

$ ls /usr/bin/gcc*

you should see 3 files: gcc, gcc-4.4, gcc-4.6.
And gcc link to gcc-4.6

Then link gcc to gcc-4.4

$ rm /usr/bin/gcc
$ ln -s /usr/bin/gcc-4.4 /usr/bin/gcc
