 Using BOOST_FOREACH in VC8/9 with warning level 4 and code analysis
 enabled results in some compiler warnings:

 {{{
 boost/foreach.hpp(474) : warning C4100: 't' : unreferenced formal
 parameter

 boost\foreach.hpp(414) : warning C6282: Incorrect operator: assignment of
 constant in Boolean context. Consider using '==' instead

 warning C6001: Using uninitialized memory '_foreach_end': Lines: 11, 13
 warning C6001: Using uninitialized memory '_foreach_cur': Lines: 11, 13
 }}}

 I'm not sure exactly where the 6001 warnings come from, as the real
 location is hidden by the macro.
 Note also that all but the first warning only occur when code analysis is
 enabled, so can only be reproed on a compiler version that supports that
 option.
