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
008A8994 cmp ecx,eax
008A8996 jb cs10+0Eh (08A89A2h)
008A8998 mov eax,ecx
008A899A pop ecx
008A899B xchg eax,esp
008A899C mov eax,dword ptr [eax]
008A899E mov dword ptr [esp],eax
008A89A1 ret
008A89A2 sub eax,1000h
