[Sun C++] 64-bit conversion warnings building the library
---------------------------------------------------------
Key: STDCXX-547
URL: https://issues.apache.org/jira/browse/STDCXX-547
Project: C++ Standard Library
Issue Type: Bug
Components: Build
Affects Versions: trunk
Environment: Sun C++ +w, wide mode (-xarch=amd64, -xarch=sparcv9, or
-m64)
Reporter: Martin Sebor
Priority: Minor
Fix For: 4.2
We get a bunch of 64-bit conversion warnings when building the library in wide
(64-bit) mode with Sun C++ 5.8 and 5.9:
