> Latest HP aCC 6.16 builds produce many remarks making them exceedingly noisy:
> {noformat}
> $ gunzip -c hpux-11.31-ia64-acc-6.16-12D-637671-log.gz | grep "remark #" | wc -l
> 4187
> {noformat}
> The breakdown by remark produced by the following script is in the table below:
> {noformat}
> $ W=`gunzip -c hpux-11.31-ia64-acc-6.16-12D-637671-log.gz | sed -n "s/.* remark #\([1-9][0-9]*\)-D:.*/\1/p" | sort | uniq`; \
