Hmm - where's the line complaining about the missing dll?

It already is a dependency; I just checked the setup.hint on the cygwin
site. Rerun setup.exe, and it should offer to install libsigsegv2-2.8-1
for you; I'm not sure why you missed it when you first installed, unless
you chose not to pull in all required dependency packages.
Meanwhile, a self-built m4 won't depend on libsigsegv unless you have
libsigsegv-2.8-1 installed.
