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. */ 33#if GNULIB_defined_struct_timeval 34# undef timeval 35# undef gettimeofday 36#endif 37 38#endif /* COMMON_GDB_SYS_TIME_H */ 39
