[Boost-build] MSVC toolset problem

While writing a test suite for process_jam_log I've encountered the following
problem:

(HEAD) msvc.jam defines link actions as:

     actions link bind DEF_FILE
     {
         $(.LD) $(LINKFLAGS) /out:"$(<[1]:W)" /LIBPATH:"$(LINKPATH:W)" $(OPTIONS) @"@($(<[1]:W).rsp:E=$(nl)"$(>)" $(nl)$(LIBRARIES_MENTIONED_BY_FILE) $(nl)$(LIBRARIES) $(nl)"$(LIBRARY_OPTION)$(FINDLIBS_ST:S=.lib)" $(nl)"$(LIBRARY_OPTION)$(FINDLIBS_SA:S=.lib)")"
         if exist "$(<[1]).manifest" (
             $(.MT) -manifest "$(<[1]).manifest" "-outputresource:$(<[1]);1"
         )
     }

On my system (WinXP Pro SP2) the last line ("if exist ...") makes cmd to
return 0 exit code instead of error code from linker, causing
process_jam_log to incorrectly report this failure.

The following workaround gets around this by explicitly exiting if link failed:

     actions link bind DEF_FILE
     {
         $(.LD) $(LINKFLAGS) /out:"$(<[1]:W)" /LIBPATH:"$(LINKPATH:W)" $(OPTIONS) @"@($(<[1]:W).rsp:E=$(nl)"$(>)" $(nl)$(LIBRARIES_MENTIONED_BY_FILE) $(nl)$(LIBRARIES) $(nl)"$(LIBRARY_OPTION)$(FINDLIBS_ST:S=.lib)" $(nl)"$(LIBRARY_OPTION)$(FINDLIBS_SA:S=.lib)")"
         if errorlevel 1 exit %errorlevel%
         if exist "$(<[1]).manifest" (
             $(.MT) -manifest "$(<[1]).manifest" "-outputresource:$(<[1]);1"
         )
     }
