* instead of /usr/include use the current SDK path as system include directory (/usr/include is empty with current tools) (this also removes the need to add these paths in individual Makefiles) * define _DARWIN_C_SOURCE in tcc.h to get the full set of decls from system headers (e.g. vsnprintf), similar to _GNU_SOURCE (and don't define _ANSI_SOURCE in the main Makefile anymore) * tests/tests2/Makefile: remove the -w flag, it's added when necessary in the rules generating the .expect files
