?S:d_getlogin_r:
?S:	This variable conditionally defines the HAS_GETLOGIN_R symbol,
?S:	which indicates to the C program that the getlogin_r()
?S:	routine is available.
?S:.
?S:getlogin_r_proto:
?S:	This variable encodes the prototype of getlogin_r.
?S:	It is zero if d_getlogin_r is undef, and one of the
?S:	REENTRANT_PROTO_T_ABC macros of reentr.h if d_getlogin_r
?S:	is defined.
?S:.
?C:HAS_GETLOGIN_R:
?C:	This symbol, if defined, indicates that the getlogin_r routine
?C:	is available to getlogin re-entrantly.
?C:.
?C:GETLOGIN_R_PROTO:
?C:	This symbol encodes the prototype of getlogin_r.
?C:	It is zero if d_getlogin_r is undef, and one of the
?C:	REENTRANT_PROTO_T_ABC macros of reentr.h if d_getlogin_r
?C:	is defined.
