*
* buildno - Generate the build number for ReactOS
*
* Copyright (c) 1999,2000 Emanuele Aliberti
*
* License: GNU GPL
*
* It assumes the last release date is defined in
* <reactos/version.h> as a macro named
*
* KERNEL_RELEASE_DATE
*
* as a 32-bit unsigned long YYYYMMDD (UTC;
* MM=01-12; DD=01-31).
*
* The build number is the number of full days
* elapsed since the last release date (UTC).
*
* The build number is stored in the file
* <reactos/buildno.h> as a set of macros:
*
* KERNEL_VERSION_BUILD base 10 number
* KERNEL_VERSION_BUILD_STR C string
* KERNEL_VERSION_BUILD_RC RC string
*
* REVISIONS
* ---------
* 2000-01-22 (ea)
* Fixed bugs: tm_year is (current_year - 1900),
* tm_month is 0-11 not 1-12 and code ignored TZ.
* 2000-12-10 (ea)
* Added -p option to make it simply print the
* version number, but skip buildno.h generation.
