[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: 4.1.4, 4.1.3, 4.1.2
Environment: Sun C++ 5.9, wide (64-bit) mode
Reporter: Martin Sebor
Priority: Minor
Attachments: suncc-64-bit-warnings.txt
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.
