Last change on this file since 6b1931b was 96b89acb, checked in by Martin Decky <martin@…>, 15 years ago
  • check compatibility of the compiler's wchar_t and wint_t
  • simplify integer types detection
  • invert the preference of integer types (shorter types are now prefered over longer types)
  • Property mode set to 100755
