12# Configure will issue a WHOA warning. The problem is that

14# environment, you can set d_tzname='define' since tzname[] is
15# available in the System V environment.

18# Configure will issue a WHOA warning. The problem is that unistd.h
19# contains incorrect prototypes for some functions in the usual
20# BSD-ish environment. In particular, it has
21# extern int getgroups(/* int gidsetsize, gid_t grouplist[] */);
22# but groupslist[] ought to be of type int, not gid_t.
23# This is only really a problem for perl if the
24# user is using gcc, and not running in the SysV environment.
25# The gcc fix-includes script exposes those incorrect prototypes.
26# There may be other examples as well. Volunteers are welcome to
27# track them all down :-). In the meantime, we'll just skip unistd.h
bd89102f 28# for SunOS in most of the code. (However, see ext/POSIX/hints/sunos_4.pl.)

33You will probably see *** WHOA THERE!!! *** messages from Configure for
34d_tzname and i_unistd. Keep the recommended values. See
35hints/sunos_4_1.sh for more information.

38# The correct setting of groupstype depends on which version of the C
39# library is used. If you are in the 'System V environment'
40# (i.e. you have /usr/5bin ahead of /usr/bin in your PATH), and
41# you use Sun's cc compiler, then you'll pick up /usr/5bin/cc, which
42# links against the C library in /usr/5lib. This library has
43# groupstype='gid_t'.
44# If you are in the normal BSDish environment, then you'll pick up
45# /usr/ucb/cc, which links against the C library in /usr/lib. That
46# library has groupstype='int'.
47#
48# If you are using gcc, it links against the C library in /usr/lib
49# independent of whether or not you are in the 'System V environment'.
50# If you want to use the System V libraries, then you need to
51# manually set groupstype='gid_t' and add explicit references to
52# /usr/5lib when Configure prompts you for where to look for libraries.

65# If you get the message "unresolved symbol '__lib_version' " while
66# linking, your system probably has the optional 'acc' compiler (and
67# libraries) installed, but you are using the bundled 'cc' compiler with
68# the unbundled libraries. The solution is either to use 'acc' and the
69# unbundled libraries (specifically /lib/libm.a), or 'cc' and the bundled
70# library.
