I know.  That was in the message I quoted... and I cloned the repository 
also quoted in that message, the Makefile doesn't have MXE_TARGETS (in 
branch master).

Not in the repository I cloned.  Just to be precise, I used this 
command, which shows the repository you mentioned:

git clone -b master git://github.com/tonytheodore/mxe.git

or you meant a different branch?  instead of "multi-rebase" is it 
"multi-target"?
