I succeed in building tcl/tk within binutils sources under windows
(cygwin) by replacing the default version of tcl/tk with the last one
from sourceforge. BTW, I wonder why FSF tcl source is not up-to-date in
binutils sources, but this is out of topic here. License issue ?

It seems too complicated for my use...

I think I need to properly setup the testsuite on the cygwin computer
first (running native mingw32 toolchain).
