[FlopCpp] problem compiling examples

[Michal Kaut]

I have found a way around the problem, by using a Makefile for examples 
in another Coin-OR project. Still do not know why the original does not 
work, though.. But I wander why it can't be the same as in the other 
projects (which works OK).

I am attaching a Makefile that works for (my installation of) 
MinGW+MSYS. Note that to use it, one would have to edit the COININCDIR 
and COINLIBDIR entries.
