C-c C-c killing gdb on OS/X

[John Wiegley]

To any of the Mac developers:

If I write a program that waits in a loop, and hit C-c C-c while in
gdb under gud, gdb will terminate with:

  C-c C-c
Debugger finished

But I do the same thing in the Terminal, it interrupts the program as
I expect.

Ideas?  I checked process.c, and it doesn't seem that anything is
being done differently for darwin.
