CC can have multiple sub-strings like "ccache gcc". Erorr pops up if it is treated as single string and double quote are used around it. This can be fixed by removing the quotes and not treating CC a single string.

The intent is testing if $CC is set. Does this change work when $CC is not set?

More by luck than judgement. Before and after. If $CC might be empty you probably want:

[ -n "$CC" ] && { echo 0; return; }

The subject is also wrong. Should be "allow field splitting' of ${CC}. (no brace or curly braces, not round ones.)

Good points. It would be good enhancement to add the check - since the current logic doesn't handle the null CC

I'll send a V2.
