Last change on this file since 6ab8697 was 6ab8697, checked in by Martin Decky <martin@…>, 16 years ago

use builtin_va_* for va_* functions and va_list type
(this is probably safer than our own implementation since it respects the particular ABI used by the compiler)
this fixes kernel printf() when using clang
  • Property mode set to 100644
