right, now it works.

I was thinking of some things i forgot to mention. You can supply your own
new and delete (called __builtin_new and __builtin_delete). That way you can
write debug versions and keep track of all your memory leaks, just like MFC.
Ive tacked on some bodies I copied out of an old libgcc, but looking at it
again they're a bit forgiving.

Also, you might need to supply your own code for calling global
constructors. this should do the trick;

//define these outside of main() in the same file
// __CTOR_LIST__ symbol created by linker
typedef void (*func_ptr) (void);
extern func_ptr __CTOR_LIST__[];

// put the next bit of code in main() after InitHeap but before everything
else.
unsigned int nptrs;
nptrs=(unsigned int)__CTOR_LIST__[0];
 if  (nptrs==(unsigned int)-1)
 {
  // on others, it is -1 and you see how many
  // pointers there are because the array is
  // null terminated
  nptrs=0;
  while (__CTOR_LIST__[nptrs+1]!=NULL)
  {
   nptrs++;
  }
 }
   // Call the initialisation functions in reverse order (?)
 for (h=nptrs; h>=1; h--)
 {
  __CTOR_LIST__[h]();
 }

You won't need this if you dont have any global constructors. Helpfully, if
you give ld the flag --warn-constructors it'll tell you if you have some.

Oh and remember to unzip the zip in the root directory.

yours compilerly
