I won't have time to check this until tomorrow, but I'm guessing that the 
following patch will fix the problem:

--- a/src/emacs.c
+++ b/src/emacs.c
@@ -170,7 +170,7 @@ #define MAIN_PROGRAM
     We mark being in the exec'd process by a daemon name argument of
     form "--daemon=\nFD0,FD1\nNAME" where FD are the pipe file descriptors,
     NAME is the original daemon name, if any. */
-#if defined NS_IMPL_COCOA || (defined HAVE_NTGUI && defined CYGWIN)
+#if defined NS_IMPL_COCOA || defined CYGWIN
  # define DAEMON_MUST_EXEC
  #endif

My guess is based mostly on the fact that the problem doesn't occur in emacs-w32 
(i.e., when HAVE_NTGUI is defined).  Please give this a try if you have a chance 
before I get to it.
