shift operator problem 0.4.5c 20141012

[GoogleCodeExporter]

What steps will reproduce the problem?

In older versions this code worked (note spaces around >> )
set /a M=*0x8298 & 0xffffffff >>10+1 > nul && set /a M1=*0x82c0>> 10+1 > nul
set /a M=%M% + %M1% > nul
set B64=[%M%MB %B64%]

But in new version I have to remove the spaces to make it work

set /a M=*0x8298 & 0xffffffff>>10+1 > nul && set /a M1=*0x82c0>>10+1 > nul
set /a M=%M% + %M1% > nul
set B64=[%M%MB %B64%]

What is the expected output? What do you see instead?

expected 1152MB (old grldr)
but new version shows 1178561MB

new grldr not compatible with old versions.
if remove spaces then new version also prints 1152MB

What version of the product are you using? On what operating system?
0.4.5c 20141012

Please provide any additional information below.

0.4.6a 20141015 also has same issue

This version corrupts ?_BOOT variable same as before
all NNNNNNNN with sedillas

It does however continue with the commands in the checkaccess.g4b batch file 
and continue with the commands in the menu.lst.

So it almost works - just that ?_BOOT is getting corrupted.

I don't know why variable lost,may be there is BUG ins BIOS or GRUB4DOS has 
hidden unknown bug.

Please try this,if still corrupts i think is unable to solve current.
