The best idea IMO is to check for "bool".  If it's not there, typedef 
it.  If it is, just use it as is (even some pre-C99 compilers have it.) 
 It's just a single autoconf line:

  AC_CHECK_TYPES(bool)

Then in your header file:

  #ifndef HAVE_BOOL
  enum booleanValues { false, true };
  typedef enum booleanValues bool;
  #endif

Then simply use bool, true and false as if you're always on C99 or C++.
