SANE does not allow c++ external backend ( epkowa for epson V200)

Some Epson scanners ( Perfection V100, V200, etcc )  need  an external library  and the corresponding firmware from epson site  ( package iscan  and iscan-plugin ).
On gentoo, debian based  and rpm based  distrib, sane is compiled to allow such things
Stock sane from  sane.org and  arch  does not seem  to link with the c++ backend  epkowa  provided  by  epson

xsane work fine  but   scanimage -L  not ( scanimage is necessary for scripting ) 
To use an epson  external firmware based scanner , one  have to  compile  sane  by hand
and modify  frontend/Makefile   
LINK = $(CC)  [...]    need to be replaced  by  LINK = g++  [ ... ] 

Lost several hours to figure out where was the prb,  cause the epkowa  sane backend used to work  out of the box on other distrib
