OK, thanks.

The warning is not bogus when you are compiling with --disable-checking
or when your GCC_VERSION is < 2007. This is because the way
linemap_assert is defined:
/* Assertion macro to be used in line-map code. */
#define linemap_assert(EXPR) \
do { \
if (! (EXPR)) \
abort (); \
} while (0)
/* Assert that MAP encodes locations of tokens that are not part of
the replacement-list of a macro expansion. */
#define linemap_check_ordinary(LINE_MAP) __extension__ \
({linemap_assert (!linemap_macro_expansion_map_p (LINE_MAP)); \
(LINE_MAP);})
#else
#define linemap_assert(EXPR)
#define linemap_check_ordinary(LINE_MAP) (LINE_MAP)
#endif
In those cases token_no is not used. Hence the fix committed to
revision 180090.
Sorry for the inconvenience.
