int/double conversion when initializing an array

[GoogleCodeExporter]

The attached program gives different output when run from python and when
run under shedskin.

An array of doubles is initialized with an integer, and the type conversion
doesn't work correctly.

It appears to be a problem with variadic functions and type conversions (in
the list constructor).  See the attached vatest.cpp file.

One possible solution is to add explicit casts in the constructor call, eg
  charges = (new list<double>(1,(double)6));

hi mark,

thanks for noting this problem, and the proper solution. I will go over all 
variadic
functions and add casts where necessary before the next release :)

note that the code you comment out with 'this (correctly) doesn't compile' 
could be
made to compile, too, by converting the integer list to a double list at 
run-time..
