"a:" means have a and the current directory.

So this is not a bug, C_INCLUDE_PATH acts just like PATH in that an empty
argument after the colon means the current directory.

There are a bunches of way of checking if C_INCLUDE_PATH is set, like
$(?C_INCLUDE_PATH) I think will tell you if it is set or not.  This is not the
right forum to ask about shell programming really.
