I'm using Swig and bbv2 and i use .i as suffix for swig input file. This 
was working well in the past but with latest bbv2 i got an error : 
preprocessed.jam already define this suffix.

type.register SWIG : i ;
generators.register-standard alma.swig : SWIG : CPP ;

feature.feature swig-options : : free ;
toolset.flags alma.swig OPTIONS <swig-options> ;

rule swig { }
actions swig {
         swig  $(OPTIONS) -o $(<) $(>)
}

C:/Renaud/alma/BuildTools/bbv2/build\type.jam:123: in register-suffixes 
from module type
error: Attempting to specify multiple types for suffix "i"
error: Old type PREPROCESSED_C, New type SWIG
C:/Renaud/alma/BuildTools/bbv2/build\type.jam:58: in type.register from 
module type

What should i do ?
- Change my swig suffix to something more explicit (.swig_i)
- or can i disable PREPROCESSED_C.

Thanks
