I just tried this myself and it seems that with Python 2.7 __name__ is never 
equal to '__main__' in jcc's __init__.py. So, jcc.__main__ is never imported 
implicitely from __init__.py and hence --find-jvm-dll is ineffective.

I moved the --find-jvm-dll trickery to __init__.py and that seems to solve 
the problem. Of course, this is all masked if the PATH already contains the 
JRE directories.
