I tracked the problem down to the 'link' and 'archive' actions
which uses RSP files with the msvc toolset but not with gcc. 

Adding

generators.register-linker msvc.link "" : RSP : EXE : <toolset>intel ;
generators.register-linker msvc.link "" : RSP : SHARED_LIB IMPORT_LIB : <toolset>intel ;
generators.register-standard msvc.archive : RSP : STATIC_LIB : <toolset>intel ;

solves this problem but now the actions are evaluated in the 'msvc' namespace
and changed variables for the linker are not used. 

My current test version of intel.jam is now

---------------------------------------------------------------------------
import generators ;
import toolset : flags ;

toolset.register intel ;
toolset.inherit intel : msvc ;

rule init ( )
{
.CC = icl ;
}

generators.register-linker msvc.link "" : RSP : EXE : <toolset>intel ;
generators.register-linker msvc.link "" : RSP : SHARED_LIB IMPORT_LIB : <toolset>intel ;
generators.register-standard msvc.archive : RSP : STATIC_LIB : <toolset>intel ;

---------------------------------------------------------------------------

having a simple Jamfile :

---------------------------------------------------------------------------
project hello ;

obj hello : hello.cpp : <toolset>msvc ;
obj h2 : h2.cpp : <toolset>intel ;
exe Hello : hello h2 ;
---------------------------------------------------------------------------

causes errors because 'msvc' and 'intel' are not regarded as link-compatible.

Any hints on how to solve this? 

How should the 'vendor' variable from the 'msvc' toolset be set by the
'intel' toolset so that the link-compatibility is established (as suggested by
David Abrahams) ?

Is the problem with RSP generators a bug or how do I have to import the
msvc.link and msvc.archive generators so that local variable settings are
respected?
