# Configure will issue a WHOA warning.  The problem is that
# Configure finds getzname, not tzname.  If you're in the System V

# 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.

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.

# If you get the message "unresolved symbol '__lib_version' " while

# unbundled libraries (specifically /lib/libm.a), or 'cc' and the bundled
# library.
