ba7bde0bdf VERSION=x.yy must set the setver-able DOS version, not the "true internal" 
DOS version. The setver-able version is the one queried by int 21.30 and
settable by int 21.33fc, internal version is the one queried by int 21.3306.

265efa8b8b removed the "protect 386 registers" patch again, a fixed version of free- 
EMM386 is available. This reduces device driver call overhead in terms of
CPU and stack usage.  Older EMM386 versions destroyed eax ebx ecx edi esi
ebp fs gs, now go_driver_entry in emm386.asm saves those registers. Only
the INIT was broken, but the execrh.asm patch protected ALL functions.

40276450af changed the os_release version message to be 
"build 2036 cvs [version Sep 09 2005 compiled May 20 2006]" as opposed to
the old "version 1.1.35 (Build 2035b-cvs) [Jul 23 2005 12:34:56]"
-> removed the "1.1.35" and compile TIME, added SOURCE DATE
