Who are you apologizing to? If you had problems sending no one would have
seen them.

Maybe at some point someone will actually do it right and try to submit
patches to gdb.

CTRL-C works fine on cygwin. I use it all of the time.

cygwin signals from the inferior process. I haven't looked at what
mingw does but it is likely to be the same code.
