This sounds a lot like the weird "dereferencing pointer to incomplete
type" errors gcc was giving me. I think the problem is that struct
_HTStyle (like struct _HTStream) is not defined in any header file. My
analysis was that this is because of the lib's pseudo C++ system; by not
defining _HTStyle, you can redefine it in any subclass of HTStyle
[Eric?], just like _HTStream is redefined in all the different stream

Anyway, try putting

	struct _HTStyle {};

somewhere near the top of your file.

This probably will cause problems if you are allocating HTStyles or
accessing fields in the HTStyle (I haven't used styles, so I can't say).

Also, have a look at the C/C++ Style document at w3's web site, maybe it
says something about this.
