13 ?S: This variable conditionally defines the HAS_GETGRENT_R symbol,
14 ?S: which indicates to the C program that the getgrent_r()
15 ?S: routine is available.
18 ?S: This variable encodes the prototype of getgrent_r.
19 ?S: It is zero if d_getgrent_r is undef, and one of the
20 ?S: REENTRANT_PROTO_T_ABC macros of reentr.h if d_getgrent_r
24 ?C: This symbol, if defined, indicates that the getgrent_r routine
25 ?C: is available to getgrent re-entrantly.
28 ?C: This symbol encodes the prototype of getgrent_r.
29 ?C: It is zero if d_getgrent_r is undef, and one of the
30 ?C: REENTRANT_PROTO_T_ABC macros of reentr.h if d_getgrent_r
