I knew I had seen this already ;-) And now I found it. The problem
has been discussed in april last year in fr.comp.tex.text

http://groups.google.com/group/fr.comp.text.tex/browse_thread/thread/8a570e588c5670fe/fdd526ffe7fc10e6?hl=de&ie=UTF-8&oe=utf-8

In this thread the source of the problem was that the (old) tex
engine doesn't understand the %&latex notation. You had to force
metapost to use pdftex. Either by setting the environment variable
TEX:

I:\Z-Test>set TEX=pdftex

I:\Z-Test>mpost test2.mp

or by calling mpost with the -tex=pdftex option:

I:\Z-Test>mpost -tex=pdftex test2
