D shared libraries

[Unknown W. Brackets]

Windows is a huge ordeal.  I'm more interested right now in fixing it on 
Linux (I do not write many Windows programs anyway, and the differences 
between so and dll are many.)

I realize there are runtime issues, but I'm concerned mainly about the 
reason why dmd on Linux is unable to create shared objects, while gdc 
can (although there are many complications.)
