Odd; that says all your dlls are in place.  The only other thing that I
can suspect is that you have an incomplete dll, where you are missing a
required entry point (perhaps you are running too old of a
cygwin1.dll?).  What is $? after the failed m4?  Also, can you try
opening up a cmd window, and running m4 from there, to see if you get a
useful popup box? (running under a cygwin shell intentionally suppresses
dll link error popup boxes)

Posting your 'cygcheck -svr' output would help, as well.
