Actually adding this to the Jamfile:

<toolset>sun:<define>__typeof__=__typeof__

is a better workaround because having __typeof__ defined will prevent
Boost.Config from defining it to "typeof":

...
#  ifndef __typeof__ 
#     define __typeof__ typeof // boost/config/platform/linux.hpp:103 
#  endif 
...

So Boost.Typeof will be able to use Sun's native __typeof__ :)

We still should fix the actual issue in Boost.Config -- but I'm not sure
how... maybe replacing __GNUC__:

// boost/config/platform/linux.hpp
#ifndef __GNUC__ 
// 
// if the compiler is not gcc we still need to be able to parse 
// the GNU system headers, some of which (mainly <stdint.h>) 
// use GNU specific extensions: 
// 
//... 
#  ifndef __typeof__ 
#     define __typeof__ typeof // boost/config/platform/linux.hpp:103 
#  endif 

with:

#if !defined(__GNUC__) && (!defined(__SUNPRO_CC) || __SUNPRO_CC < 0x590)

Note that Sun has __typeof__ since version 5.9.

But I'm not familiar enough with the Boost.Config platform stuff to make any
change to it... any taker?

Thanks.
