Theoretically that's possible by altering the setup.py script: we must  
check the platform of the user and if it's Windows and we're building  
the Windows installer, we must add libxml2.dll and iconv.dll to the  
list of files to be installed. However, there are some minor flaws:

1. These DLLs get installed in the same directory where the files of  
the package will be. (Python root\Lib\site-packages\igraph). This can  
be considered an advantage or a disadvantage as well: clearly we're  
wasting space, but we can be sure that the required libraries are  
installed along with the package. Alternatively, we could try to infer  
the full path of the system32 subdirectory somehow and install our  
DLLs there, risking that we're overwriting a previous version of  
libxml2.

2. The two DLLs are roughly 2 Mbytes, therefore effectively doubling  
the size of the package.
