This file must be translated to C and modified to build everywhere.

Run flex like this:

  flex --prefix=cmCommandArgument_yy --header-file=cmCommandArgumentLexer.h -ocmCommandArgumentLexer.cxx cmCommandArgumentLexer.in.l

Modify cmCommandArgumentLexer.cxx:
  - remove TABs
  - remove "yyscanner" argument from these methods:
      yy_fatal_error, cmCommandArgument_yyalloc, cmCommandArgument_yyrealloc, cmCommandArgument_yyfree
  - remove all YY_BREAK lines occurring right after return statements
  - change while ( 1 ) to for(;;)

Modify cmCommandArgumentLexer.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)
