Not picking up the correct GCC verison

I am running an environment which requires an older version of gcc (gcc.4.8.3 to be exact).

I have this version of gcc sitting at location: /usr/local/bin (see below)

I have appended /usr/local/bin to my $PATH file so that this directory is checked for a version of gcc first - so picking up the gcc.4.8.3 version (see below)

However when I check the version of gcc I still see the latest version gcc.4.9.3 referenced and not gcc.4.8.3.(see below)

How can I reference version gcc.4.8.3 using my $PATH file?
