As I've mentioned in a couple other threads, I am beginning to develop a D compiler for that targets the .net framework. I have a little experience toying with a much simpler programming language (that I created) which compiles to msil.

So far I have the lexer mostly done. basically what I did was look at the dmd front end and figured out what it's doing, and rewrote it in C#. I didn't exaclty convert the code from C to C# (although it looks like it in some areas), but used the code in lexer.c as a basis for mine. is that legal? I do have a comment at the top that indicates the code is based on what Walter Bright wrote in lexer.c.

currently I don't have a liscense for my code.. I'm just developing this alone for now, and I won't be releasing anything, source code or binary, until it is liscensed. when it is though, it will be open source. probably gpl.

the front end is GPL

If you do a derived work from the frond end, which is GPL, then the result must be GPL as well. Doing a translation is considered a "derived work."
