+Your cc seems to be gcc and its version seems to be less than 2.95.
+This is not a good idea since old versions of gcc are known to produce
+buggy code when compiling Perl (and no doubt for other programs, too).
+
+Therefore, I strongly suggest upgrading your gcc.  (Why don't you
+use the vendor cc is also a good question.  It comes with the operating
+system and produces good code.)
+
+Note that as of gcc 2.95 (19990728) and Perl 5.6.0 (end of March 2000)
+if the said Perl is compiled with the said gcc the lib/sdbm test will 
+dump core.  As this doesn't happen with the vendor cc, this is
+most probably a lingering bug in gcc.  Therefore unless you have
+a better gcc you are still better off using the vendor cc.
+
+Cannot continue, aborting.
