It doesn't give permission to modify, either, or (of course) to redistribute modified copies.
There may be other grants of permission outside of that header which might grant such permissions. Is there a full statement of license anywhere? Are there other statements from TI floating about the web which say that the file can be modified and redistributed?
It might be possible to simply obtain a statement of these permissions from TI.

The file is (or, rather, was) distributed as a "related download" alongside the TI-83+ SDK. We (that is, the calculator hacking community) did some digging and found the full license terms on a cached version of the download page for the SDK, but they are extremely restrictive: see https://github.com/alberthdev/spasm-ng/issues/37#issuecomment-243555962. (Note that some related discussion is going on in that ticket).
It isn't entirely clear, though, if this license just applies to the SDK or if it also applies to the include file and all the other "related downloads" on the SDK page.
If there are any other statements from TI on this issue, I'm not aware of them, unfortunately.
We could attempt to contact TI, I suppose. There are people in the calculator hacking community who have a reasonably good relationship with people who work for their calculator division.
