WARNING
=======
Libpng 1.5 erroneously uses /MD when building debug DLL versions of libpng.
It should use /MDd - you can change this under properties\C/C++\Code
Generation\Runtime Library if you need to use the debug runtime for debug
builds. This will be changed in libpng 1.6 but is currently retained for
compatibility with older libpng 1.5 releases.
The runtime library settings for each build are as follows:
Release Debug
DLL /MD /MD
Library /MT /MTd
The Visual Studio 2010 defaults for a Win32 DLL or Static Library project are
as follows:
Release Debug
DLL /MD /MDd
Static Library /MD /MDd
Notice that by default static library builds use the DLL runtime, not the
static library runtime.
