Hmm, yes, that's true :-)
Thanks for it.

The problem would still be present for users of version 2.1.25.
No need to add SASL_CALLBACK_FT_DEFINED.  I will use:

  #ifdef HAVE_SASL
  # include <sasl/sasl.h>
  # include <sasl/saslplug.h>
  # include <sasl/saslutil.h>
  /* For Cyrus SASL versions < 2.1.24. */
  # ifndef sasl_callback_ft
  typedef int (*sasl_callback_ft)(void);
  # endif
  #endif

It seems to work fine.  (And more readable than testing 
SASL_VERSION_MAJOR, SASL_VERSION_MINOR, and SASL_VERSION_STEP.)

I wish you a nice week,
