I'm trying to give the option to run ccache all day instead of typing in each time to use ccache while I compile, "temp env"
if I do export gcc="ccache gcc" or would alias be better?

In this case, I think you'd be best off setting your CC variable, like this:

 export set CC='ccache gcc' 

I've never used ccache before, though, so someone correct me if I'm wrong.

Actually when you do the export gcc="ccache gcc" you just create the environment variable. To refer this variable from command prompt you need to place $ sign before it name. This is a little bit unusable, I think it is better to use alias gcc="ccache gcc" command instead of export.

Yeah, that was the point - Makefiles inheriting the CC env var, instead of using shell aliases, which they often ignore. but you're definitely right, from the cmd line, the alias way makes more sense.
