45 Notes:
46
47 If you change anything in the source files, or select different compiler
48 settings, please change the DLL name to something different than any of
49 the above names. Also, make sure that in your "pngusr.h" you define
50 PNG_USER_PRIVATEBUILD and PNG_USER_DLLFNAME_POSTFIX according to the
51 instructions provided in "pngconf.h".
52
53 All DLLs built by this project use the Microsoft dynamic C runtime library
54 MSVCRT.DLL (MSVCRTD.DLL for debug versions). If you distribute any of the
55 above mentioned libraries you should also include this DLL in your package.
