Building without Emacs malloc, possible?

[Jan Djärv]

Hello.

What is the status of building without Emac malloc?  There are some problems 
on cygwin + Gtk.  Basically Gtk+ (glib actually) calls memalign, but on cygwin 
this does not call the Emacs supplied memalign, but cygwins own.  Since malloc 
is the one Emacs has, cygwin memalign refuses to work.  I don't know why the 
Emace memalign is not called, dynamic libraries on W32 seems to behave strange 
in this regard.

One solution would be for Emacs to not use its own malloc, but that gives 
compilation errors.  I don't have the errors here, but they are unresolved 
symbols in vm-limit.c.

So, the question is what is need to compile on cygwin without Emacs malloc? I 
just added

#define SYSTEM_MALLOC

to s/cygwin.h.  Apparently something more is needed.
