  16. /* On MinGW-w64, gnulib's sys/time.h replaces 'struct timeval' and
  17. gettimeofday with versions that support 64-bit time_t, for POSIX
  18. compliance. However, the gettimeofday replacement does not ever
  19. return time_t values larger than 31-bit, as it simply returns the
  20. system's gettimeofday's (signed) 32-bit result as (signed) 64-bit.
  21. Because we don't really need the POSIX compliance, and it ends up
  22. causing conflicts with other libraries we use that don't use gnulib
  23. and thus work with the native struct timeval, such as Winsock2's
  24. native 'select' and libiberty, simply undefine away gnulib's
  25. replacements. */
