But drawstuff has already included this, and uses these functions? I
can't include them again in my own program, that gives me more obscure
messages.

No.. maybe that's what I'm misunderstanding.. ?

Just that it couldn't find the file "vector", if I remember correctly.
And when I specified the full path, I got lots of syntax and not
defined- errors from within the vector-file. I guessed the makefile used
a C-only compiler, which didn't understand the C++ in Vector.
