-# FreeBSD has the dynamic loading dl*() functions in /usr/lib/crt0.o,
-# so Configure doesn't find them (unless you abandon the nm scan).
+# Additional 2.0.5 and 2.1 defined from
+# Ollivier Robert <Ollivier.Robert@keltia.frmug.fr.net>
+# Date: Fri, 12 May 1995 14:30:38 +0200 (MET DST)

+# Additional 2.2 defines from

+# Date: Wed, 6 Nov 1996 09:44:58 +0200 (MET)
+# 
 # The two flags "-fpic -DPIC" are used to indicate a
 # will-be-shared object.  Configure will guess the -fpic, (and the
 # -DPIC is not used by perl proper) but the full define is included to 
 # be consistent with the FreeBSD general shared libs building process.
 #
-# setreuid and friends are inherently broken in all versions of FreeBSD.
+# setreuid and friends are inherently broken in all versions of FreeBSD
+# before 2.1-current (before approx date 4/15/95). It is fixed in 2.0.5
+# and what-will-be-2.1
