Comment(by bryan@…):
Last time I looked at it, admittedly about ten years ago, flex++ generated
lexer code that was usable from a C++ program. flex generated C code
only, which might or might not work when compiled as C++, depending on the
compiler and the code that got generated.
Looking for more current info, I see on wikipedia the claim that flex++
will generate a couple of classes that can be used from the program.
Classes being a C++ thing only, obviously plain flex doesn't do that.
From [http://linux.die.net/man/1/flex++], I see that the -+ or --c++ flags
appear to do the same thing, so flex inspecting argv[0] and automatically
treating one of those flags as set when it's called as flex++, seems
likely to me.
