[patch] SPU time cleanup
- From: Ken Werner <ken at linux dot vnet dot ibm dot com>
- To: newlib at sourceware dot org

- Subject: [patch] SPU time cleanup
Hi,
Some of the functions declared by time.h are not implemented on the spu
target. This patch undefines _POSIX_TIMERS for the SPU and implements stubs for
the remaining functions.
Regards
Ken
