- Change `scc_macro_table_t` to `scc_pp_macro_table_t` for consistency - Rename `scc_pp_macro_create` to `scc_pp_macro_new` for naming convention - Remove unused `scc_pp_compress_whitespace` function - Update macro table function names: `scc_pp_find_macro` → `scc_pp_macro_table_get`, `scc_pp_remove_macro` → `scc_pp_macro_table_remove` - Add new `scc_pp_macro_table_set` function for setting macros - Update all function signatures to use new type name - Remove commented-out whitespace compression code from implementation
