+While running Configure and when building, you are likely to get
+quite a few of these warnings:
+
+  ld:
+  The shared object /usr/lib/libm.so did not resolve any symbols.
+        You may want to remove it from your link line.
+
+Ignore them: in IRIX 5.3 there is no way to quieten ld about this.
+
+During compilation you will see this warning from toke.c:
+
+  uopt: Warning: Perl_yylex: this procedure not optimized because it
+        exceeds size threshold; to optimize this procedure, use -Olimit option
+        with value >= 4252.
+
+Ignore the warning.

 In IRIX 5.3 and with Perl 5.8.1 (Perl 5.8.0 didn't compile in IRIX 5.3)
 the following failures are known.
