silenced truncation warnings on i386 targets
silenced truncation warnings on i386 targets

Code using xorg-gtest and compiling on 32-bit x86 targets using
GCC 4.7 or later get a truncation warning setting timeouts for
sigtimedwait().  If the code sets -Werror this is fatal.

This patch prevents those warnings.
