Teach cmListFileLexerDestroy to call cmListFileLexerSetToken with a NULL
token to free the token string buffer. Without this, if an error occurs
before the token cleanup happens when EOF is reached, then the token
string buffer may leak.
Teach the lexer to return tokens for whitespace. Teach the parser to
tolerate the space tokens where whitespace is allowed. Also teach the
parser to diagnose and warn about cases of quoted arguments followed
immediately by another argument. This was accidentally allowed
previously, so we only warn.
Update the RunCMake.Syntax test case StringNoSpace expected stderr to
include the warnings.
If a line inside a string ends in a backslash count the following
newline character as a line increment. Add a test covering this case to
verify that subsequent line numbers are correct.
In each .l and .y input file that has instructions for manual
transformation of the output to include a step to remove the 'register'
storage specifier.
This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
