Even if you can compile it to binary, it still won't run correctly because  
of the dmc codegen problem.

I will attach a compilable nedmalloc source, corresponding compile batch,  
and a simple test app. In two post of this thread because of the  
attachment size limitation of 51k.

The bug is:

malloc.c.h:1870          
interlockedcompareexchange(&malloc_global_mutex_status, -1, 0) == 0) {
004020f7: 837dfc00                cmp dword [ebp-0x4], 0x0
004020fb: 7530                    jnz 0x40212d  init_malloc_global_mutex  
malloc.c.h:1875
004020fd: 6a00                    push 0x0
004020ff: 6aff                    push 0xff
00402101: 68b8e74200              push dword 0x42e7b8
00402106: e811100200              call 0x42311c  
__InterlockedCompareExchange

*Notice:

The prototype of the func for last two params are longs. So it should be:

push 0x00000000
push 0xffffffff

not:
push 0x0
push 0xff
