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.

==========
FreeBSD:
autoconf 2.52 creates scripts that are incompatible with the Posix
(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
