    this affects you, downgrading to autoconf 2.13 (which is installed
    on Darwin) will help.
 
+   With Leopard (at least up to 10.5.2), when running configure
+   you will likely see errors such as:
+
+      rm: conftest.dSYM: is a directory
+
+   This is a known issue and will be fixed in a later version of the
+   autoconf suite. These errors can be safely ignored.
+
+   With Darwin 10, the default C compiler (gcc) will try to build
+   multi-architecture bundles. This causes problems with APR, which
+   needs to know various data-type sizes which it assumes are universal
+   for platforms. Until this is fully fixed, we recommend using the
+   '-arch i386' gcc option when building both Apache and APR.

+================
+  AIX, using the vendor C compiler with optimization:
+    There is an issue with compiling server/core.c with optimization enabled
+    which has been seen with C for AIX 5.0.2.3 and above.  (5.0.2.0, 5.0.2.1,
+    and 5.0.2.2 have an additional problem with Apache 2.0.x, so either upgrade 
+    the compiler or don't use optimization in order to avoid it.)
+
+    cc_r works fine with -O2 but xlc_r does not.  In order to use xlc_r with
+    -O2, apply the patch at 
+
+    http://www.apache.org/dist/httpd/patches/apply_to_2.0.49/aix_xlc_optimization.patch
+
+    (That patch works with many recent levels of Apache 2+.)
 
+================
+  Solaris:
+
+    On Solaris, better performance may be achieved by using the Sun Studio
+    compiler instead of gcc.  As of version 11, it is now free (registration
+    required).  Download the compiler from:
+
+    http://developers.sun.com/prodtech/cc/downloads/index.jsp
+
+    If you use Sun Studio, the following compiler flags (CFLAGS) are
+    recommended:
+
+      -XO4 -xchip=generic
+
+================
+  Ubuntu:
 
+    You will need to ensure that you have either libtool 1.5.6
+    or 2.2.6b, or later. Expat 2.0.1 and PCRE 8.02 are also
+    recommended to be installed. If building PCRE from source,
+    you'll also need g++.
