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