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.

Run flex like this:
|
|
|
|
flex --prefix=cmExpr_yy --header-file=cmExprLexer.h -ocmExprLexer.cxx cmExprLexer.in.l
|
|
|
|
Modify cmExprLexer.cxx:
|
|
- remove TABs
|
|
- remove "yyscanner" argument from these methods:
|
|
yy_fatal_error, cmExpr_yyalloc, cmExpr_yyrealloc, cmExpr_yyfree
|
|
- remove all YY_BREAK lines occurring right after return statements
|
|
- change while ( 1 ) to for(;;)
|
|
|
|
Modify cmExprLexer.h:
|
|
- remove TABs
|
|
- remove the yy_init_globals function
|
|
- remove the block that includes unistd.h
|
|
- remove #line directives (avoids bogus warning on old Sun)
