This is a question for Cygwin developers, not for Emacs developers.
ecrt0.c is the startup code, which is typically called by the OS after
it loads the executable.  In the Cygwin case, ``the OS'' is probably
some Cygwin module, which is in turn called by Windows.  But that's
guesswork; someone who is privy to Cygwin internals should answer your
question.
