Okey. You should use "modify_type" function transformation with
"remove_const" type traits function.

Untested:

from pygccxml import declarations
from pyplusplus import module_builder
from pyplusplus import function_transformers as FT

mb = module_builder_( ... )
f = mb.mem_fun( 'f' )
f.add_transformation( FT.modify_type(0, declarations.remove_const ) )
#0 - argument index

HTH
