  Changes between 0.9.2b and 0.9.3
 
+  *) New config option to avoid instructions that are illegal on the 80386.
+     The default code is faster, but requires at least a 486.
+     [Ulf Möller]
+  
   *) Got rid of old SSL2_CLIENT_VERSION (inconsistently used) and
      SSL2_SERVER_VERSION (not used at all) macros, which are now the
      same as SSL2_VERSION anyway.

  This will build and install OpenSSL in the default location, which is (for
  historical reasons) /usr/local/ssl. If you want to install it anywhere else,
- do this after running `sh config':
+ do this after running `./config':
 
   $ perl util/ssldir.pl /new/install/path
 
+ There are several options to ./config to customize the build:
+
+  -DRSAref  Build with RSADSI's RSAREF toolkit.
+  no-asm    Build with no assembler code.
+  386       Use the 80386 instruction set only (the default x86 code is
+            more efficient, but requires at least a 486).
+
  If anything goes wrong, follow the detailed instructions below. If your
  operating system is not (yet) supported by OpenSSL, see the section on
  porting to a new system.
