BUG: Reimplemented ExpandListArguments to properly handle escaped backslashes that occur right before semicolons.  This is important for lists of paths ending in backslashes on windows.

ERR: Renaming cmListFileLexer.l to cmListFileLexer.in.l to avoid make programs trying to run lex automatically whn building cmListFileLexer.c.

ENH: Using lex-based tokenizer and a simple recursive-descent parser in place of the old hand-coded parser for CMake listfiles.

ENH: Improved error messages when source tree does not have a CMakeLists.txt file.  No matter how many cases we check, there always seems to be a user that finds a case that gives a confusing error message...

ENH: Removed pipe selection argument from WaitForData method in kwsysProcess.  This greatly simplifies its use.

BUG: Process startup-info struct dwFlags were being set incorrectly due to a change in statement order.

ERR: Some platforms define stdin, stdout, and stderr as macros.  Renaming these symbols to StdIn, StdOut, and StdErr.

ENH: Merged changes from KWSys-MultiProcess-bp to KWSys-MultiProcess-b2t-1-mp to main tree.  This introduces support for process pipelines.
