[HP aCC 6.15] lots of noise due to compiler remarks
---------------------------------------------------

                 Key: STDCXX-695
                 URL: https://issues.apache.org/jira/browse/STDCXX-695
             Project: C++ Standard Library
          Issue Type: Bug
          Components: Build
    Affects Versions: 4.2.0
         Environment: HP aCC 6.15
            Reporter: Martin Sebor


The latest HP compiler on IPF issues lots of remarks, making our builds 
exceedingly noisy.

Here's a breakdown of all the remarks we get in a recent 12S build along with 
the number of each:

F=hpux-11.31-ia64-acc-6.15-12S-610576-log; \
R=`sed -n "s/.*: remark \(#[1-9][0-9]*-.\): .*/\1/p" $F | sort | uniq`; \
for r in $R; do \
    n=`grep ": remark $r: " $F | wc -l`; echo $r: $n; \
done

#2177-D: 8   variable was declared but never referenced
#2181-D: 9   argument is incompatible with corresponding format string 
conversion
#2550-D: 28   variable was set but never used
#2826-D: 44   parameter was never referenced
#2961-D: 1   use of a type with no linkage to declare a variable with linkage
#3235-D: 1   nonstandard conversion between pointer to function and pointer to 
data
#3348-D: 799   declaration hides constant or variable
#4217-D: 3   comparison of enum (represented as an unsigned integer) with zero
#4219-D: 250   64 bit migration: type conversion may truncate value
#4234-D: 28   type conversion may lose significant bits
#4239-D: 2   case type mismatch with switch expression type
#4244-D: 4   extern storage class used with a function definition
#4248-D: 4   comparison of unsigned integer with a signed integer
#4271-D: 780   type conversion may lose sign
#4273-D: 18   floating-point equality and inequality comparisons may be 
inappropriate due to roundoff common in floating-point computation
#4278-D: 3   the subexpression in logical expression is a constant
#4282-D: 34   virtual function is called from constructor/destructor
#4283-D: 3   access global variable in constructor
#4296-D: 695   arithmetic operation on boolean type
#4297-D: 1220   boolean value is used as array index
#4298-D: 124   64 bit migration: addition result could be truncated before cast 
to bigger sized type
#4299-D: 20   64 bit migration: multiply result could be truncated before cast 
to bigger sized type
#4300-D: 60   Overflow while computing constant in left shift operation
#4315-D: 60   while loop without body, did you insert an extra ';'?
