+# 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

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

+# 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.
