50f75b6e8a
with my changed code. - Cleaned up DECORATE parser a little - moved the old style parsing code into its own file and rearranged a few things. - Made ProcessStates non-static so that it doesn't need to be passed as an argument to all functions in the DECORATE parser. - Moved DECORATE parser files into their own subdirectory. - Optimization: SC_GetToken no longer sets sc_name for identifiers. In most cases this creates needless overhead by adding a potentially unneeded name to the name table and looking up the name. In almost all cases where a name is needed it's as easy to assign sc_String to the name variable. - Added enum definitions to DECORATE. SVN r537 (trunk)
