The above description (even though is a good one) alone would leave
the reader wondering if this patch now has removed the last use of
strtoull(), removing the need to have NO_STRTOULL in the Makefile
and configure.ac, and also wonder why the patch does not touch
Makefile etc.  Something like

	We still use strtoull() as a part of the compatibility
	implementation of strtoumax(), so we cannot remove the
	support to detect/configure the use of the function in the
	Makefile and autoconf, though.

may deserve to be made into the second paragraph that follows the
above description.

Shouldn't the type of some variables in the codepath also be changed
to make sure we receive the return value from the function in a
variable that is large enough?

Thanks.
