8705,BOOST_PP_ENUM_SHIFTED doesn't work with Intel ICC,pascal@…,No-Maintainer,"Consider this example:

{{{
#include <boost/preprocessor/repetition.hpp>

#define F(z, n, p)              n
#define INNER_NORMAL(z, n, p)   f( BOOST_PP_ENUM(n, F, p) ) ;
#define INNER_SHIFTED(z, n, p)  f( BOOST_PP_ENUM_SHIFTED(n, F, p) ) ;

shifted:
BOOST_PP_REPEAT(4, INNER_SHIFTED, ~)

expected:
INNER_SHIFTED(~, 0, ~)
INNER_SHIFTED(~, 1, ~)
INNER_SHIFTED(~, 2, ~)
INNER_SHIFTED(~, 3, ~)

normal:
BOOST_PP_REPEAT(4, INNER_NORMAL, ~)
}}}

With `clang++ -P -E` and `g++ -P -E` it expands correctly:

{{{
shifted:
f( ) ; f( ) ; f( 1 ) ; f( 1 , 2 ) ;
expected:
f( ) ; f( ) ; f( 1 ) ; f( 1 , 2 ) ;
normal:
f( ) ; f( 0 ) ; f( 0 , 1 ) ; f( 0 , 1 , 2 ) ;
}}}

But `icpc -P -E` gets stuck:

{{{
shifted:
f( BOOST_PP_ENUM_SHIFTED_1_2(0, F, ~) );
f( BOOST_PP_ENUM_SHIFTED_1_2(1, F, ~) );
f( BOOST_PP_ENUM_SHIFTED_1_2(2, F, ~) );
f( BOOST_PP_ENUM_SHIFTED_1_2(3, F, ~) );
expected:
f(  ); f(  ); f( 1 ); f( 1, 2 );
normal:
f(  ); f( 0 ); f( 0, 1 ); f( 0, 1, 2 );
}}}

I'm using *Intel(R) C++ Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 13.1.1.163 Build 20130313*, not sure if it's a bug in ICC or in Boost.Preprocessor;
