- add <stdarg.h> or <varargs.h> in snprintf.h and remove those inclusions in the other #ifdef NEED_SNPRINTF_H codes - remove the check of multiple inclusions in source (.c) code (there is a bit loss of _cpp_ performance, but I prefer the gain of code reading and maintenance; and nowadays, disk caches and VM are correctly optimized ;-). - protect all (well almost) header files against multiple inclusions - add header (i.e. GPL license) in some include files - reorganize a bit the way header files are included: First: #include <system_include_files> #include <external_package_include_files (e.g. gtk, glib etc.)> Then #include "ethereal_include_files" with the correct HAVE_XXX or NEED_XXX protections. - add some HAVE_XXX checks before including some system header files - add the same HAVE_XXX in wiretap as in ethereal Please forgive me, if I break something (I've only compiled and regression tested on Linux). svn path=/trunk/; revision=2254
