#5887: Pidgin does not work on 64-bit userland PowerPC systems

 Reporter:  JoseJX     |       Type:  patch

 '''The problem:'''

 On 64-bit systems, time_t is a 64-bit value.  time_t is used as a hash key
 in savedstatuses.c, but the g_hash_table is implemented using a 32-bit
 hash key value.  Additionally, all of the preferences save these keys as
 32-bit values.  Unfortunately, the first word is used on 64-bit
 architectures. On little endian systems, these are the LSB and no problem
 is visible.  On big endian 64-bit systems, the values used for the hash
 key are the MSB and do not change, leading to collisions, etc.

 This manifests as looping for a *very* long time when adding new hash
 elements, as well as segfaults due to an inability to match keys.

 '''Proposed solution:'''

 Change the current usage of time_t in saved_statuses to unsigned int.
 This fixes the observed issue on ppc64.
