Create a self contained object file like fat jars from java

[pizza_dox_9999]

OK to make it clear. I wanted to call d from c so that I can 
write a n64 game with d. But compiling the d object files while 
using higher features like classes, resulted in missing 
dependencys. So because GCC doesnt understands d I need an object 
file which has everything included d needs to run. Thats my 
understanding of this situation.
