---------------------------------
Resolution: Fixed
> [Sun C++] 64-bit conversion warnings building utilities
> -------------------------------------------------------

> Key: STDCXX-550
> URL: https://issues.apache.org/jira/browse/STDCXX-550
> Project: C++ Standard Library
> Issue Type: Bug
> Components: Utilities
> Affects Versions: 4.1.2, 4.1.3, 4.1.4
> Environment: Sun C++ 5.9, wide (64-bit) mode
> Reporter: Martin Sebor
> Assignee: Eric Lemings
> Priority: Minor
> Fix For: 4.2.2
>
> Attachments: suncc-64-bit-warnings.txt
>
> Original Estimate: 2h
> Time Spent: 8h
> Remaining Estimate: 0h
>
> Compiling the utilities with Sun C++ in wide (64-bit) mode produces a large
> number of warnings of the type: Conversion of 64 bit type value to "unsigned"
> causes truncation. Most of these might be benign and can be silenced by
> adding appropriate casts but there might be some, especially those involving
> unsigned char, that should be reviewed more carefully to make sure they don't
> indicate real problems. For example, the localedef utility should validate
> data read from character set description files and locale definition files to
> make sure it's in the range of unsigned char (or 8 bit unsigned integer type
> to be precise) and issue diagnostics for values that exceed this range.
