If I run `gdb > emacs`, gdb gives "Error creating process /usr/local/bin/emacs, (error > 5)." when I type the `run` command, but it can run emacs if I specify > the name of the binary to which `emacs` is a symlink > (/usr/local/bin/emacs -> /usr/local/bin/emacs-24.4.50.exe).

I was running whatever was current at the time. But there is a bug in GDB 7.8 that prevents you from using it to debug a GUI version of emacs. See https://sourceware.org/bugzilla/show_bug.cgi?id=17247#c34. Until this is fixed, you need to downgrade to the previous release of GDB. Ken
