Thanks to Inge Gutheil for raising this problem. * doc/ref/api-control.texi (Dynamic Wind): Remove doc for scm_t_dynwind_flags, and change uses of scm_t_dynwind_flags to int. Mention possible flags inside doc for scm_dynwind_begin instead. Similarly for scm_t_wind_flags. In this case the doc on possible flags is moved to after the four functions that can use them. * libguile/dynwind.c (scm_dynwind_begin): Change scm_t_dynwind_flags to int. (scm_dynwind_unwind_handler): Change scm_t_wind_flags to int. (scm_dynwind_rewind_handler): Ditto. (scm_dynwind_unwind_handler_with_scm): Ditto. (scm_dynwind_rewind_handler_with_scm): Ditto. * libguile/dynwind.h (SCM_F_DYNWIND_REWINDABLE): Use #define instead of typedef enum. (SCM_F_WIND_EXPLICITLY): Ditto. (function declarations): Change scm_t_dynwind_flags and scm_t_wind_flags to int. * test-suite/standalone/test-unwind.c (check_cont_body): Change scm_t_dynwind_flags to int.
