+As an extension the integer scalar type @code{__int128} is supported for
+targets having an integer mode wide enough to hold 128-bit.
+Simply write @code{__int128} for a signed 128-bit integer, or
+@code{unsigned __int128} for an unsigned 128-bit integer. There is no
+support in GCC to express an integer constant of type @code{__int128}
+for targets having @code{long long} integer with less then 128 bit width.
