That makes the wording describing the max macros more awkward, since it's
now following a list of four rather than two, but here is a version that
lists the GNU names like that.

[BZ #5461]
* manual/arith.texi (strtoll): Refer to LLONG_MAX and LLONG_MIN,
not LONG_LONG_MAX and LONG_LONG_MIN.
* manual/lang.texi (LONG_LONG_MIN): Document first as ISO
LLONG_MIN. Refer to LONG_LONG_MIN only as older GCC-specific
name.
(LONG_LONG_MAX, LLONG_MAX, ULONG_LONG_MAX, ULLONG_MAX): Likewise.

This is the minimum value that can be represented by a @w{@code{signed
long long int}}. On most machines that the GNU C system runs on,
@w{@code{long long}} integers are 64-bit quantities.
+@code{LLONG_MIN} is the ISO C name for this value. An older

+@code{LONG_LONG_MIN}; this was the only name available with GCC
