[HP aCC 6.15] many remarks in builds

                 Key: STDCXX-788
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Build
    Affects Versions: 4.2.0
         Environment: aCC: HP C/aC++ B3910B A.06.16 [Nov 26 2007]

            Reporter: Martin Sebor
            Assignee: Martin Sebor
            Priority: Minor

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

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; \
