Hitchikers Guide to Porting Phobos / D Runtime to other architectures

[Iain Buclaw]

I got asked whether there are any porting hints for phobos on 
other architectures the other day from the debian GCC 
maintainers.  So I gathered this must be at least a dedicated 
wiki or article to be written up on the subject. :)

I know there are a few working on porting gdc and associated 
libraries over to ARM (with my assistance from the compiler 
side).  So please tell, what are your experiences? Successes?  
Failures?  What tips would you give to someone wanting to port to 
their own architecture?
