Need help building emacs with system malloc

Wed Dec 9 15:52:00 GMT 2009

Emacs by default uses its own malloc, but the emacs developers have 
suggested that I try to build it so that it uses Cygwin's malloc. (See 
http://lists.gnu.org/archive/html/emacs-devel/2009-12/threads.html#00369 
for the context if you're curious.) When I try to do this, the build 
fails as follows:
gcc -o temacs ecrt0.o dispnew.o frame.o scroll.o xdisp.o menu.o 
window.o charset.o coding.o category.o ccl.o character.o chartab.o cm.o 
term.o terminal.o xfaces.o emacs.o keyboard.o macros.o keymap.o 
sysdep.o buffer.o filelock.o insdel.o marker.o minibuf.o fileio.o 
dired.o filemode.o cmds.o casetab.o casefiddle.o indent.o search.o 
regex.o undo.o alloc.o data.o doc.o editfns.o callint.o eval.o 
floatfns.o fns.o font.o print.o lread.o syntax.o unexcw.o bytecode.o 
process.o callproc.o region-cache.o sound.o atimer.o doprnt.o strftime.o 
intervals.o textprop.o composite.o md5.o sheap.o terminfo.o 
lastfile.o vm-limit.o getloadavg.o -lcurses -lg `gcc 
-print-libgcc-file-name` -lm -lc `gcc -print-libgcc-file-name`
vm-limit.o:vm-limit.c:(.text+0x17): undefined reference to 
`___after_morecore_hook'
vm-limit.o:vm-limit.c:(.text+0x6c): undefined reference to `___morecore'
Is this one of those situations where the libraries are listed in the 
wrong order in the gcc command? Or is there something else going on? 
I'm attaching my .cygport and .src.patch files in case it's more subtle 
and someone else wants to give it a try.
