| 11:29 | [1632447]: Allow the PPM maxval to go up to 65535, to conform with a format definition change from around 2000 (even if that's a rare format). check-in: 85a3e256 user: dkf tags: core-8-5-branch | |

| 08:51 | Put extern "C" guards around all stub table struct definitions, so it is usable to be used for C++ compilers as well without the danger of modifying the calling convention. For tkDecls.h, ttkDecls.h tkIntXlibDecls.h is was no problem, because tk.h, tkTheme.h and Xlib.h already contain those guards. But not for the other *Decls.h files. check-in: 39acb6d0 user: jan.nijtmans tags: core-8-5-branch | |
