You are rigth.
My problem (an undefinite symbol, and only one) was due to a problem in 
my mingw installation.
I was confused because boost has a build procedure and tools (with 
configure and makefiles).
It seems this build is not really necessary.

Now I know the problem (at link time) is due to libstdc++ and 
differences between version from gcc 3.4 a nd 4.2.

My mingw installation mixes gcc 3.4 (the default, easy to install) and 
gcc 4.2..1 (install by hands, but i prefer this this version because it 
detects more errors than gcc 3.4 ).
And this creates a problem for one library: libstdc++ (i believe gcc 
4.2.1 used some 3.4.1 libraries, in my mingw install).

I found the same problem under linux if I mix libstdc++ version 3.4 and 
compilation under gcc 4.1

But this problem is specific to my kicad static build (i use static link 
with as many libraries as possible, to avoid library version problems, 
for end users).
When using the "normal" build (using current libraries from the linux 
distribution), it works fine.
