Re: Using multiple linkers

I think I have figured out a cleaner way to do it. 

==== mgcc.jam ==== 
import "class" : new ; 
import toolset ; 
import generators ; 
import common ; 

toolset.register mgcc ; 

import gcc ; 
toolset.inherit-generators mgcc : gcc : gcc.compile.c 
gcc.compile.c++ gcc.link gcc.link.dll ; 
toolset.inherit-flags mgcc : gcc ; 
toolset.inherit-rules mgcc : gcc ; 

rule init ( version ? : command * : options * ) 
{ 
local condition = [ common.check-init-parameters mgcc : version 
$(version) ] ; 
local command = [ common.get-invocation-command mgcc : g++ : 
$(command) ] ; 

common.handle-options gcc : $(condition) : $(command) : 
$(options) ; 

gcc.init-link-flags gcc gnu $(condition) ; 
} 

generators.register-c-compiler gcc.compile.c++ : CPP : OBJ : ; 
generators.register-c-compiler gcc.compile.c : C : OBJ : ; 

generators.register [ new gcc-linking-generator gcc.link : LIB OBJ : 
EXE 
: <linker>gcc ] ; 

generators.register [ new gcc-linking-generator gcc.link.dll : LIB 
OBJ : SHARED_LIB 
: <linker>gcc ] ; 
===== mgcc.jam end ===== 

In addition I have added linking rules into ifort.jam. 
Now it is possible to select a specific linking method just as I 
described before. 

However I am still trying to figure out a somewhat cleaner way to do 
it: I don't like that I had to introduce new toolset for it -- I 
would prefer much more to be able to simply add this "<linker>gcc" 
requirement to generators (already) registered by gcc toolset. Is it 
possible? Or I should modify gcc.jam from distribution? 

I do not completely understand when I should use gcc or mgcc in init 
fuction. Present combination works fine, but I don't really 
understand why ;)
