I'm sure, given the context, that David's comment that "there is no
standard here" was exclusively about the signedness of char, and that he
did not intend for that comment to apply to the signedness of 'int'.
This difference between "char" and "int" is one of the key reasons why
"char is a smaller int" fails to be completely accurate.

Actually, no.  "char", "signed char", "unsigned char", "int", "signed
int" and "unsigned int" are all equally syntactically valid. 6.7.2p5,
which says that "Each of the comma-separated multisets [in 6.7.2p2]
designates the same type, except that for bitfields,", is in the
semantics section, not the syntax section. "int" is in the same multiset
with "signed int", but "char" is in a multiset all of it's own.
