Yes, that's intentional.  NUL and null are alternate spellings for
the same character. I went with nul to distinguish it from the null
pointer and used all lowercase as per the GCC convention.

Can you elaborate which guideline suggests spelling that in lowercase?
It seems quite strange to me, especially given that the documentation
added with the patch uses "NUL character" (which I believe to be a more
common form), but then warnings use "nul" (without the "character" iiuc).

I don't know if there is a specific guideline that applies here,
but it's my impression that conventionally GCC messages use
lowercase letters.  The only guideline I know about is in the GNU
Coding Standard that calls for messages not to begin with capital
letters (or end in a period;  though now that I've checked more
carefully there are a fair number of messages that ignore that

That said, if the lowercase nul is offensive it can certainly be
changed to some other spelling (as can any of the other messages
emitted by the pass).


PS Yes, the C and C++ standards refer to NUL as the null character.
NUL is an abbreviation, used extensively (for example) by POSIX.
