src/temacs:

I've done a few tests which suggest the problems with the missing title bar etc. that I reported are a separate issue.  I did a build targeted to 10.6 instead of 10.7 after removing the -fno-pie, and I had no problems unexecing, but the title bar was still gone.

I also tried running src/emacs directly (a 10.7 build with -fno-pie).   It printed this to the console:

2011-07-10 08:04:33.093 emacs[61589:707] ERROR: Can't have a toolbar in a window with <NSNextStepFrame: 0x100e40830> as it's borderview

I'll try that later; I'll have to pull plain emacs 24 code as this doesn't seem to work with the Aquamacs code base.
