On my computer, Cygwin GCC tell:
	gcc (GCC) 4.3.4 20090804 (release) 1

- After some hours of work, I find the way to built PCB.  But it is really
   dirty.  Here what I have done:

	- Done a "./configure" using the following command:

		"./configure --disable-update-mime-database --disable-update-desktop-database 
--disable-nls --disable-update-xdg-database --prefix=/usr/local/geda"

	- In "src/core_lists.h", removed the last line
	  ("REGISTER_ACTIONS (toporouter_action_list)").

	- Do a "make".
	  Note: This result to a link error at the end.

	- Grab (stdout) messages given by "make", and use it to create a
	  custom manual link (through a shell script), replacing bad references
	  to local libraries.  Ex.: Replacing "libgtk.a", by "-lgtk".
	  Also removing "toporouter.o" that seems to refer to objects that
	  can not be found anywhere!?

	- Do a "make install".


- I will try your workaround.


Thank you for your help.
Claude.
