<p>LLVM sets certain default configure options to make sure our developers don't
break things for constrained platforms. These settings are not optimal for most
desktop systems, and we hope that packagers (i.e., Redhat, Debian, MacPorts,
etc.) will tweak them. This document lists settings we suggest you tweak.

<dt>RTTI</dt><dd>LLVM disables RTTI by default. Add <tt>REQUIRES_RTTI=1</tt>
to your environment while running <tt>make</tt> to re-enable it. This will
allow users to build with RTTI enabled and inherit from LLVM classes.</dd>
<dt>Exceptions</dt><dd>LLVM disables exceptions by default. Add
<tt>REQUIRES_EH=1</tt> to your environment while running <tt>make</tt> to
re-enable them. This will allow users to link LLVM and exception-using code.
It also re-enables RTTI.</dd>

<p>Configure with <tt>--enable-shared</tt> to build
<tt>libLLVM-<var>major</var>.<var>minor</var>.(so|dylib)</tt> and link the tools
against it. This saves lots of binary size at the cost of some startup time.
