> Porting Issue -- Visual Studio compiler requires explicit casts
> ---------------------------------------------------------------
>
> Key: PROTON-98
> URL: https://issues.apache.org/jira/browse/PROTON-98
> Project: Qpid Proton
> Issue Type: Improvement
> Components: proton-c
> Environment: Windows using Visual Studio 2010
> Reporter: Mary hinton
> Labels: build
> Attachments: explicitCasts2.patch, ExplicitCasts.patch
>
>
> I would like to get the code changed to add explicit casts where the Visual
> Studio compiler requires it.
> The GNU compiler isn’t so picky, but we need the explicit casts for Visual
> Studio tools.
> The problem is in many of the files.
