That's yet another case of a non-Cygwin program expecting to talk to a
Windows console rather than the pipes underlying Cygwin's pseudo
terminal device implementation. Even runas's help output doesn't work
in mintty, which suggests that it's using console-specific functions
for all its I/O.

Not within it, but you could invoke mintty itself as administrator
with right-click->Run As or by changing its shortcut to invoke it
through runas.
