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

Run flex like this:

  flex --prefix=cmDependsJava_yy --header-file=cmDependsJavaLexer.h -ocmDependsJavaLexer.cxx cmDependsJavaLexer.in.l

Modify cmDependsJavaLexer.c:
  - remove TABs
  - remove "yyscanner" argument from these methods:
      yy_fatal_error, yyalloc, yyrealloc, yyfree
  - remove all YY_BREAK lines occurring right after return statements

Modify cmDependsJavaLexer.h:
  - remove TABs
  - remove the yy_init_globals function
  - remove the block that includes unistd.h
