17 # unistd.h contains incorrect prototypes for some functions in the usual
18 # BSD-ish environment. In particular, it has
19 # extern int getgroups(/* int gidsetsize, gid_t grouplist[] */);
20 # but groupslist[] ought to be of type int, not gid_t.
21 # This is only really a problem for perl if the
22 # user is using gcc, and not running in the SysV environment.
23 # The gcc fix-includes script exposes those incorrect prototypes.
24 # There may be other examples as well. Volunteers are welcome to
25 # track them all down :-). In the meantime, we'll just skip unistd.h
26 # for SunOS in most of the code.
27 # However, see ext/POSIX/hints/sunos_4.pl for one exception.

35 # 64, but only 32 of those file pointers can be accessed
36 # directly by _iob[i]. The remainder are off in dynamically
37 # allocated memory somewhere and I don't know to automatically
