Milestone:  To Be Determined                |   Component:  random

--------------------------------------------+-------------------------------
 The following minimal program

 {{{
 #include "boost/random/xor_combine.hpp"

 int main() {}
 }}}

 gives a lengthy compiler error (Tested with Visual studio 2008 and mingw
 gcc 4.8):

 {{{
 boost\random\xor_combine.hpp|144|error: 'os' has not been declared|
 boost\random\xor_combine.hpp|144|error: 's' has not been declared|
 boost\random\xor_combine.hpp|144|error: ISO C++ forbids declaration of
 'BOOST_RANDOM_DETAIL_OSTREAM_OPERATOR' with no type [-fpermissive]|
 boost\random\xor_combine.hpp|153|error: 'is' has not been declared|
 boost\random\xor_combine.hpp|153|error: 's' has not been declared|
 boost\random\xor_combine.hpp|153|error: ISO C++ forbids declaration of
 'BOOST_RANDOM_DETAIL_ISTREAM_OPERATOR' with no type [-fpermissive]|
 [snip]
 }}}

 which can be traced down to the missing definition of the macro
 BOOST_RANDOM_DETAIL_OSTREAM_OPERATOR (and presumably some others), which
 are defined via

 {{{
 #include "boost/random/detail/operators.hpp"
 }}}

 Indeed adding this include before the other one fixes the problem.
