| 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 |
