I suggest that you check to see that you have enough swap space. Since you
don't have very much memory (e.g. 4megs) and I suspect that GNU-emacs
has some pretty big files, its possible that you don't have enough swap
space to compile it. Because AIX doesn't preallocate swap space this is
usually evidenced by a Memory fault at run time when the system has to 
page out part of your process (the compiler) and there isn't enough 
swap space (BSD at least tests before it gives you the memory so that 
once processes are given memory the system doesn't usually have to send
a nasty signal to the process later on). Another possiblity if you can't
easily add swap space is to get rid of all expendable processes to
increase the available swap space. In particular, if you're running X windows,
shut it down while you do the compile. Also you might be able to cut the
compiler memory requirements by dropping out -O (if you're using that).
