12# Configure will issue a WHOA warning. The problem is that
13# Configure finds getzname, not tzname. If you're in the System V
14# environment, you can set d_tzname='define' since tzname[] is
15# available in the System V environment.

54000519 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

28# for SunOS in most of the code. The POSIX extension is built with
29# unistd.h because, even though unistd.h has problems, if used with
30# care, it helps create a better POSIX extension.

35You will probably see *** WHOA THERE!!! *** messages from Configure for
36d_tzname and i_unistd. Keep the recommended values. See
37hints/sunos_4_1.sh for more information.

52# If you get the message "unresolved symbol '__lib_version' " while
53# linking, your system probably has the optional 'acc' compiler (and
54# libraries) installed, but you are using the bundled 'cc' compiler with
55# the unbundled libraries. The solution is either to use 'acc' and the
56# unbundled libraries (specifically /lib/libm.a), or 'cc' and the bundled
57# library.
