System: Slackware Linux (version 14.2)
CPU: Intel(R) Core(TM) Duo CPU T2500 @2.00GHz
Deps: plan9port-20140306.tgz


I recently compiled plan9port-20140306.tgz with Slackware-14.2's glibc-2.23.

The plan9port files' compilation produced terminal output as follows:

9c  sam.c
/usr/include/features.h:148:3: warning: #warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]
# warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE"

The suggestion has been forwarded to avoid the deprecated function usleep() in favour of
nanosleep(), the change of the feature test macro (FTM) appears to have occurred in glibc
subsequent to Slackware-14.1's glibc-2.17, so the warnings likely do not occur with those
