/usr/include/features.h:398:52: error: operator '&&' has no right operand
 398 | #if defined _FILE_OFFSET_BITS && _FILE_OFFSET_BITS == 64

Hi. This happens because at such point _FILE_OFFSET_BITS is defined but
having an empty value.

The attached patch might help, but you might want to double-check.
as I'm no expert at modifying autoconf macros.

Thanks.
