I don't know if it came from last revision, but in version 17.0.0, when using codejock as a dll, by default (it seems), symbols from internal png lib are exported. So if you used the codejock dll with a software that has already used its own libpng dll, it may conflict in link because of multiple symbols definition.

To avoid that, i have defined in pnglibconf.h in your environment

#define PNG_IMPEXP

Because you have undefined some features from libpng (like PNG_STDIO_SUPPORTED), your internal version of the lib is not usable in every case. So, could you please avoid to export libpng symbols by default.
