14 * Revision 42.6 2004/06/16 20:16:48 verhaegs
15 * Use METHODPROTO, METHOD_END and REGFUNCPROTOn where needed.
17 * Revision 42.5 2003/01/18 19:09:56 chodorowski
18 * Instead of using the _AROS or __AROS preprocessor symbols, use __AROS__.
20 * Revision 42.4 2000/08/09 11:45:57 chodorowski
21 * Removed a lot of #ifdefs that disabled the AROS_LIB* macros when not building on AROS. This is now handled in contrib/bgui/include/bgui_compilerspecific.h.
23 * Revision 42.3 2000/05/29 00:40:23 bergers
24 * Update to compile with AROS now. Should also still compile with SASC etc since I only made changes that test the define __AROS__. The compilation is still very noisy but it does the trick for the main directory. Maybe members of the BGUI team should also have a look at the compiler warnings because some could also cause problems on other systems... (Comparison always TRUE due to datatype (or something like that)). And please compile it on an Amiga to see whether it still works... Thanks.
26 * Revision 42.2 2000/05/15 19:27:01 stegerg
27 * another hundreds of REG() macro replacements in func headers/protos.
29 * Revision 42.1 2000/05/14 23:32:47 stegerg
30 * changed over 200 function headers which all use register
31 * parameters (oh boy ...), because the simple REG() macro
32 * doesn't work with AROS. And there are still hundreds
33 * of headers left to be fixed :(
35 * Many of these functions would also work with stack
36 * params, but since i have fixed every single one
37 * I encountered up to now, I guess will have to do
38 * the same for the rest.
40 * Revision 42.0 2000/05/09 22:09:05 mlemos
41 * Bumped to revision 42.0 before handing BGUI to AROS team
43 * Revision 41.11 2000/05/09 19:54:20 mlemos
44 * Merged with the branch Manuel_Lemos_fixes.
46 * Revision 41.10.2.2 1999/07/04 05:16:05 mlemos
47 * Added a debuging version of the function BRectFill.
49 * Revision 41.10.2.1 1998/07/05 19:26:58 mlemos
50 * Added debugging code to trap invalid RectFill calls.
52 * Revision 41.10 1998/02/25 21:12:07 mlemos
53 * Bumping to 41.10
