Sorry, I don't know what the proper base address is, how it is
decided, nor what a value causes.  If possible, could you spend
a little time to look into the rebaseall log I made?  Here it is:

http://www.jpl.org/tmp/rebaseall_log.txt

At that time, I ran `rebaseall -v' and verified it ran `rebase'
as follows:

rebase -v -n -s -4\
 -T /cygdrive/c/Users/yamaoka/AppData/Local/Temp/rebase.lst

BTW, when I run `bzr update' for the Emacs trunk, it shows a warning
that varies like:

0 [main] python2.7 1300 child_info_fork::abort: unable to remap\
_ARC4.dll to same address as parent (0xBE0000) - try running rebaseall
0 [main] python2.7 4180 child_info_fork::abort: address space needed by\
 '_socket.dll' (0x860000) is already occupied
0 [main] python2.7 8072 child_info_fork::abort: address space needed by\
 'operator.dll' (0x3D0000) is already occupied

rebaseall_log.txt shows that those DLLs were rebased into:

/usr/lib/python2.7/site-packages/Crypto/Cipher/_ARC4.dll:\
 new base = 36df0000, new size = 10000
/usr/lib/python2.7/lib-dynload/_socket.dll:\
 new base = 37170000, new size = 20000
/usr/lib/python2.7/lib-dynload/operator.dll:\
 new base = 36f90000, new size = 10000

As for "_ARC4.dll", how does "36df0000" mean "0xBE0000"?

Thanks in advance.
Regards,

P.S. I tried running rebaseall also for some files I installed in
/usr/local, but it didn't help.  What I did then was:
