Please do not post links to copyrighted books.  I don't know if that
link is legal or a copyright violation, but "some link I found with
google" is certainly inappropriate.

It is also long out of date - TCPL is historically interesting, and a
fine example of good technical writing, but not necessarily an accurate
reference of current C - it formed the basis of the C standard, but has
not been updated with the standard.

The current C standard is C17, with the last pre-certification draft
available freely and legally from the WG14 themselves at:

<http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2176.pdf>


C99, C11 and the latest draft of C2x are also available:

<http://www.open-std.org/jtc1/sc22/wg14/www/projects>

(You'll find the text in question in 6.5.8p8 and footnote 110).
