Review request for Andrew Stitcher, Alan Conway, Kenneth Giusti, Ted Ross, and
Steve Huston.
Changes
-------
Added test cases from string to float/double conversion when the value is
negative.
Summary
-------
Add special test for negative numeric strings when converting to unsigned
values. (It appears - though I could be wrong - that in basic form stringstream
does not do any special handling of negatives for different locales. That
appears only to be done for money values.)
This addresses bug QPID-3206.

> Key: QPID-3206
> URL: https://issues.apache.org/jira/browse/QPID-3206
> Project: Qpid
> Issue Type: Bug
> Components: C++ Broker, C++ Client
> Affects Versions: 0.8, 0.10
> Reporter: Gordon Sim
> Assignee: Gordon Sim
> Fix For: 0.11
>
>
> E.g.
> uint16_t i = 0;
> qpid::types::Variant v = "-5";
> i = v;
> The above results in an exception in older versions of gcc (e.g. 4.1.2) but
> sets i to 65531 on later versions (e.g. 4.4.4). This is a result of a fix to
> the gcc std library to be compliant with specification which requires
> stringstream to accept negative values even for unsigned ints (which is the
> behaviour of scanf).
