...and some are not exported at all, since they're unused on a given
platform.  Here's a list obtained using 'nm':

_nc_cap_hash_table
_nc_capalias_table
_nc_check_termtype
_nc_comment_end
_nc_comment_start
_nc_curr_col
_nc_curr_file_pos
_nc_curr_line
_nc_curr_token
_nc_disable_period
_nc_head
_nc_info_hash_table
_nc_infoalias_table
_nc_key_names
_nc_nulls_sent
_nc_oldnums
_nc_screen_chain
_nc_slk_format
_nc_start_line
_nc_suppress_warnings
_nc_syntax
_nc_tail
_nc_tinfo_fkeys
_nc_tparm_err
_nc_tracing
_nc_user_definable
