Using gcc (GCC) 4.4.6 20120305 (Red Hat 4.4.6-4), I get dozens of
warnings, all apparently coming from somewhere in the MemSet macro.
example:
pl_handler.c:301: warning: logical '&&' with non-zero constant will
always evaluate as true
Probably has something to do with:
/* \
* If MEMSET_LOOP_LIMIT == 0, optimizer
should find \
* the whole "if" false at compile time. \
*/ \
MEMSET_LOOP_LIMIT != 0) \
Cheers,
Jeff
