Modify cmListFileLexer.c:
- remove TABs
- remove use of the 'register' storage class specifier
- remove the yyunput function
- add a statement "(void)yyscanner;" to the top of these methods:
yy_fatal_error, cmListFileLexer_yyalloc, cmListFileLexer_yyrealloc, cmListFileLexer_yyfree
- remove trailing whitespace: sed -i 's/\s*$//' cmListFileLexer.c
- remove blank lines at end of file
- remove statement "yyscanner = NULL;" from cmListFileLexer_yylex_destroy
- remove all YY_BREAK lines occurring right after return statements
- remove the isatty forward declaration
- remove unnecessary cast to (int) in yy_get_next_buffer

- remove TABs
- remove use of the 'register' storage class specifier
- remove the yyunput function
- add a statement "(void)yyscanner;" to the top of these methods:
yy_fatal_error, cmListFileLexer_yyalloc, cmListFileLexer_yyrealloc, cmListFileLexer_yyfree
- remove trailing whitespace: sed -i 's/\s*$//' cmListFileLexer.c
- remove blank lines at end of file
- remove statement "yyscanner = NULL;" from cmListFileLexer_yylex_destroy
- remove all YY_BREAK lines occurring right after return statements
- remove the isatty forward declaration
