Ehem, ARM

[Andrew]

A few weeks ago I tried compiling gdc and ldc on my Debian arm 
system and they built Ok but the apps crashed when run. I think 
the error was something to do with fibres in Phobos and druntime.

I tried quickly hacking in missing architecture macros for Arm 
but I didn't know what I was doing so it didn't help.

I'd start with the runtime and Phobos before looking at obj-c 
support and I'll be delighted to test it once you have it working.

There are many more arm Linux systems as well as iOS and Android 
e.g. Raspberry pi's, other SBC's like cubieboard, arduino, 
chromebooks, chromecast, kindle etc. it's estimated that 25% of 
all laptops and 10% of servers will be arm based by the end of 
next year. D will be dead unless it supports arm.

I tried valiantly to get D working and even bought the book but 
alas I've had to abandon it for now.
