lint: warn about 'extern' declarations inside function bodies
...
https://mail-index.netbsd.org/tech-userlevel/2023/03/15/msg013727.html
The previous attempt (message 351 about 'extern' declarations outside
headers) did not cover the proposal from the tech-userlevel mailing list
but instead warns about a different usage pattern of the 'extern'
keyword.

lint: do not warn about traditional C migration in C99 mode
...
For large integer constants, the resulting type could differ between
traditional C and C90. In C99 mode, this difference is no longer
relevant since it is too far away from traditional C.

The names of the tests were misleading: 'recursive' should have been
'nested', and the interesting topic in the 'cast' tests was not the cast
but the pointer dereference.

lint: add support for C11 '_Atomic' as atomic-type-specifier
...
Following the C11 grammar, the keyword '_Atomic' needs to be a separate
syntactic category, to avoid further conflicts in the grammar.
The two newly added conflicts in the grammar would come into play when
mixing traditional C with C11, in a type name without an implicit 'int'.
If the type '_Atomic(int)*' were parsed as '_Atomic int(int)*', the
trailing '*' would be a syntax error.
