I was comparing source from Megapov 0.5a and MP+ .31 and I did notice
something particularly conspicuous.

This is the main thing that kept me from making a servicable Windows build.
There just happens to be a Windows data structure of the name BLOB. I don't
know how Jetlag handled this. Or whether it has anything to do with
anything.

That is part of the code for allowing blob objects to be used with the 
blob pattern, it has nothing to do with the rendering, creating, or 
destroying of blob objects which seems to be the problem. And that 
structure exists in other POV versions too, it is the name of the blob 
object's struct. It is normally typedef'ed in blob.h, but that 
definition is moved to frame.h in MegaPOVPlus to allow the blob pattern 
to use it without running into multiple definitions.

I see. Something to keep in mind next time I try to compile it.

The BLOB keyword does make all the Windows GUI files blow up. This is new
because frame.h is included in them, while blob.h is not. I usually just
change it globally from BLOB to BLOBA or something since my main goal to
just get a compile anyway. There are other issues to deal with before it'll
compile, but most are trivial.

Actually there is a very simple way to fix it [kludge], in frame.h just
change:

#define BlobPatternPatch

-- to: --

#ifndef POVWIN_FILE
  #define BlobPatternPatch
#endif

Now, if only the blob bug was that easy...

I'm working on it when I can. Unfortunately, school is now taking most 
of my time.

If you can call that fixing...you just disabled the blob pattern on 
Windows machines.
I would change the name "BLOB" to something like "BLOB_OBJ" or 
"META_BALL". Or maybe "GOO_BALL".

Nope, it just disables the blob pattern initialization strictly within the
Windows GUI files; POVWIN_FILE is only defined in those files.  But when
other files include it, it still in turns on the blob pattern patch. I even
went ahead and tested your demo scenes, just in case, and they work
perfectly.

I believe I like "GOO_BALL". I had already done it with the disabled blob
pattern but your right; it really isn't much of a fix. Maybe one day I might
want to try experimenting with the blob pattern.

Oh, ok...I will include that fix in my code then. I still think BLOB_OBJ 
or something would be better, but it is too much for me to do right 
now(my text editor supports regular expressions and multi-file 
operations, but I don't...yet).
