# Configure will issue a WHOA warning. The problem is that
# Configure finds getzname, not tzname. If you're in the System V
# environment, you can set d_tzname='define' since tzname[] is
# available in the System V environment.
d_tzname='undef'
# Configure will issue a WHOA warning. The problem is that unistd.h
# contains incorrect prototypes for some functions in the usual
# BSD-ish environment. In particular, it has
# extern int getgroups(/* int gidsetsize, gid_t grouplist[] */);
# but groupslist[] ought to be of type int, not gid_t.
# This is only really a problem for perl if the
# user is using gcc, and not running in the SysV environment.
# The gcc fix-includes script exposes those incorrect prototypes.
# There may be other examples as well. Volunteers are welcome to
# track them all down :-). In the meantime, we'll just skip unistd.h
# for SunOS.

cat << 'EOM' >&4
You will probably see *** WHOA THERE!!! *** messages from Configure for
d_tzname and i_unistd. Keep the recommended values. See
hints/sunos_4_1.sh for more information.

# SunOS 4.1.3 has two extra fields in struct tm. This works around
# the problem. Other BSD platforms may have similar problems.

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