Compiler Warning
Description
Latest HP aCC 6.16 builds produce many remarks making them exceedingly noisy:
$ gunzip -c hpux-11.31-ia64-acc-6.16-12D-637671-log.gz | grep "remark #" | wc -l 4187
The breakdown by remark produced by the following script is in the table below:
$ 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`; \
for w in $W; do \
printf "%s " $w && gunzip -c hpux-11.31-ia64-acc-6.16-12D-637671-log.gz | grep " remark #$w-D:" | wc -l; \
done

| 3348 | 799 | declaration hides variable |
| 4217 | 3 | comparison of enum (represented as an unsigned integer) with zero |
| 4219 | 251 | 64 bit migration: type conversion may truncate value |

| 4248 | 4 | comparison of unsigned integer with a signed integer |
| 4271 | 712 | type conversion may lose sign |
| 4273 | 18 | floating-point equality and inequality comparisons may be inappropriate due to roundoff common in floating-point computation |

| 4298 | 124 | 64 bit migration: addition result could be truncated before cast to bigger sized type |

| 4315 | 61 | loop without body, did you insert an extra ';'? |
