- Cleanup the /lib directory, by putting more 3rd-party libs in /3rdparty, and by creating a new directory called /sdk where libraries which emulate the ones in the WDK are present (Such as uuid, nt, crt, etc). - Removed lib/interlck and lib/string. - Removed math routines from lib/rtl. - Created a new library called libcntpr which is what NT/WDK use when compiling the kernel/system libraries. This is an "NT-Private" version of the CRT which is supposed to contain what we had in lib/string and lib/rtl. svn path=/trunk/; revision=26095 2007-03-14 20:24:57 +00:00			`/*`
