Multiple errors with typeof about hashmap

[hoxsiew]

I was able to finally get all this resolved. I don't know why gcc kept complaining about this, but it seems to be in the way I had declared the HASHMAP typedef with a pointer to char rather than char. I think it is just an artifact of multiple nested macros making resolution of the actual problem very difficult. It has taken me about a week of rewriting (we use hashmap a lot) but it all compiles cleanly and seems to work just fine. Still lots of tests before I can sign off on the changes, but it looks OK.
