in addition, as it is cross compilation, the executables must be run on a 
Windows CE device, so...

both. The problem is that, currently, it's a wrapper for the Windows OS 
(XP, maybe below) and the wrapper compilation is failing. Hence (I don't 
know why), running make install does not install the real binary (which is 
correctly built)

not in the case of cross compilation with mingw32ce. I run *only* make and 
here is what I get:

So, the first line is the link of my real binary (evil_suite.exe), then 
the compilation of the c wrapper is done and is failing. If I run make 
install, evil_suite.exe is not installed.

If you think that I have to paste the Makefile.am, tell me.

No problem to update libtool :) I have sent that mail to solve the 
problem.
