I don't know what you got but I'm pretty sure that I sent you 1.11.

This excerpt from gdb-ui.el might be relevant. (I think Windows doesn't have
ttys but uses pipes instead).

;;; Windows Platforms:

;;	     #endif

;; and compiling with -DUNBUFFERED while debugging.

I think these differences are due to version changes in GDB, not cygwin/MinGW

Yes, under GDB/MI in the GDB manual.
