brew not linking gcc after install? Why does brew not link gcc properly? 
What am I missing?

$&gt;brew install gcc49 --without-multilib
==&gt; Installing gcc49 from homebrew/homebrew-versions
==&gt; Downloading http://ftpmirror.gnu.org/gcc/gcc-4.9.3/gcc-4.9.3.tar.bz2
==&gt; Downloading from http://gnu.mirror.iweb.com/gcc/gcc-4.9.3/gcc-4.9.3.tar.bz2

$&gt;which gcc49   // &lt;--------- NOTHING SHOWS UP HERE
$&gt;which gcc  // &lt;--------- NOTHING SHOWS UP HERE
$&gt;


I event tried brew unlink gcc49 &amp;&amp; brew link gcc49
What am I missing?
The executables are named gcc-4.9 and not gcc
I fixed it by going to:

$&gt;cd /usr/local/Cellar/gcc49/4.9.3/bin
$&gt;ln -s gcc-4.9 gcc
$&gt;ln -s g++-4.9 g++
$&gt; cd ~
$&gt;brew link gcc
