Using a good hook and compare eax to the list will set you free.

After r28205, ntoskrnl/ke/i386/init.S has no more contents and is removed from build.
Remove it from trunk too.

Yes, the whole issue is at pushing operands to stack, performing well-
documented assembly instructions to perform the asked action (div,
mul, shl, shr, etc), and handling some special, though obvious, cases
(like if you do a shl of some longlong number by more than 64 bits,
you always end up with 0, there is no need to call math instructions
in order to compute this).
I will let you know results when I speak with SDL.

Just so people don't build up rumours, this code is located in SSCLI
2.0, in the file clr/src/vm/i386/jithelp.asm . Function names are
different, however assembly code is similar.
License issues are not fully cleared up, so opinions from people
having knowledge in this area are welcome.

Aleksey Bragin.

Hi,
Recently Betov made some accusations regarding possible usage of MS's
copyrighted code in ReactOS's CRT library (example lib/sdk/libcntpr/
math/i386/sqrt_asm.s, alldiv_asm.s, and other files).
Here is my official statement in regarding to this false accusation:
This source code originally was imported into ReactOS from SanOS
project, where it was said as having GPL license (all original
copyrights are kept). After a lot of complains from Betov (aimed at
getting attention to his own project, not at improving ReactOS),
developers thought it worths looking into the issue deeper.
I performed some investigation, and found that SDL project
(www.libsdl.org) has the same code in trunk and in v1.2 branch
(http://www.libsdl.org/cgi/viewvc.cgi/trunk/SDL/src/stdlib/
SDL_stdlib.c?view=markup).
Everyone can compare asm source code with respective functions found
in MSVC's CRT source code. It matches up to label names, however
numbers have been converted from dec to hex representation. The code
in SDL project is marked as "GPL" and author is stated as "Sam
Lantinga".
It may look like a serious problem, but in reality, the source code
of these functions is released by Microsoft in SSCLI 2.0, with a
license which allows GPLing of the source code, with one restriction:
"You may not use or distribute this Software and any derivative works
in any form for commercial purposes.".
SSCLI 2.0 can be freely downloaded by everyone, license is also
certainly available to read.
I'm going to communicate with SDL about this issue, but since ReactOS
is not used commercially, it's not a problem for ReactOS now. We are
ready to collaborate with SDL on removing this issue, if it's
considered a real problem.
With the best regards,
Aleksey Bragin.
I was finally able to compile and build the boot cd, but setup hangs when doing "Importing hivesys.inf..."
But this is another trouble, different from previous one.
And I did a complete clean before compiling.
Sincerely,
Carlo Bramini

It seems that the very last change fixed my problem.
C:\RosBE>svn up
U tools\rbuild\wineresource.cpp
Aggiornato alla revisione 28138.

Today I wasn't able to compile ROS.
I got this error:
