Summary: [C++ Windows] Windows compile latest warning summary
Key: QPID-6537
URL: https://issues.apache.org/jira/browse/QPID-6537
Project: Qpid
Issue Type: Improvement
Components: C++ Broker, C++ Client
Affects Versions: 0.33
Environment: Windows Visual Studio 2012, x64
Reporter: Chuck Rolke
Priority: Minor
Recent windows builds show some warnings in the 64-bit compiles.

2>D:\qpid\cpp\src\qpid\types\Variant.cpp(130): warning C4146:
unary minus operator applied to unsigned type, result still unsigned
2>D:\qpid\cpp\src\qpid\types\Variant.cpp(342) :
see reference to function template instantiation
'T qpid::types::VariantImpl::convertFromString<uint32_t>(void) const
' being compiled
2> with
2> [
2> T=uint32_t
2> ]
{noformat}
In this case the type is unsigned. The template applies the unary minus only to
a signed type and so the warning is for code that's never executed. Still the
warning is a nuisance and should be suppressed.

These are relatively recent additions.
