Isn't vi that text editor with two modes... one that beeps and one

I tried again to compile with GCC 4.2.1 (Apple Inc. build 5577) and  
making use of some (modern, up-to-date) C header and library files  
from MacPorts. With GTK+2 as X toolkit. Now it compiles src/xterm.c!  
In the pre-processed output I see some differences (diff GTK+2- 
GCC4.2.1 GTK+2-GCC4.0.1) by which in the end the strange and faulty  
construct appears, although I have no idea why!
(Many differences with just the use of different variants of the same  
C header file omitted.)

I'm afraid you seem to be the only one who has been having these
compilation problems (that we know of).  The useful way to tackle this
problem is to bisect until you find the first change that broke
compilation, and report that change to us.  Otherwise, there seems to be
little we can do.

I hardly remember when I last built GNU Emacs with Fink. I have an old  
emacs-23.0.94 from middle of june which uses Fink... (and this area of  
my disk is never backupped)

Xterm.c preprocessed by gcc -E does not give any hints?

Hello!

By comparing the pre-processed output from xterm.c in the simple case  
X tollkit Xaw3d I found a hint for the cause of the compile failures:  
the environment variable MACOSX_DEPLOYMENT_TARGET was set. Unsetting  
it now led to a freshly compiled GNU Emacs 23.1.90! I did it with GCC  
4.2.

Hopefully the same is true for GTK+2 – and default GCC 4.0!

By removing the before mentioned environment variable also the GTK+2  
variants compile – and dump a core when I use xkill to close them!

So this bug does not exist and might even be introduced by me! Sorry.
