Here's the _chkstk implementation:

--- f:\dd\vctools\crt\crtw32\startup\i386\chkstk.asm ---------------------------
008A8980  push        ecx  
008A8981  lea         ecx,[esp+4]  
008A8985  sub         ecx,eax  
008A8987  sbb         eax,eax  
008A8989  not         eax  
008A898B  and         ecx,eax  
008A898D  mov         eax,esp  
008A898F  and         eax,0FFFFF000h
