readImageFromFileHeapSizeStartingAt 
is defined/was defined/could be defined/who knows? differently in the thrunk svn versus what cog has/did have/might have. 

I'd suggest comparing the source in the trunk svn tree /platform/iOS/vm/src/vm/interp.c 
to understand the trunk expectations of readImageFromFileHeapSizeStartingAt and the definition in sq.h, then look at what you have 
I believe 

sqInt readImageFromFileHeapSizeStartingAt(sqImageFile f, usqInt desiredHeapSize, squeakFileOffsetType imageOffset);

is the correct flavor to address issues with 64bit computers and the like, although Cog doesn't support 64bit compiles the API was altered to ensure you could pass a desired heap size > 2GB... without the number going negative... 

since the OLD definition likely looked like this and desiredHeapSize being a signed evil entity would flipout the world when it went over 2GB and slid into a negative world...

sqInt readImageFromFileHeapSizeStartingAt(sqImageFile  f, sqInt desiredHeapSize, squeakFileOffsetType  imageOffset);

This is the last thing to make it work, so any insight into solving this last part would be greatly appreciated. I did use a 4.1 Squeak image for my VMMaker and such. But I can't figure that's what's making the error. It's in "gnu-interp.c", I think.
