Just built on my Raspberry Pi 3.  Kudos - very fast, not even a 
warning!  Now to get some Docker images and go crazy.

BTW, I got a 14,116 byte executable image with LDC but 1,958,892 
with GDC.  The GDC image (stripped) is 324,492.  I installed 
reggae on my laptop (debian) and did a "reggae --export".  Then 
using make (with ldc2) I got image of 13,088.  Using "dub -b 
release --compiler=ldc2" (same build as on Raspbian) I get image 
of 381,928.

How do I do a static linkage using LDC?  I need a static because 
I want to try and run this with an Alpine (arm) Docker image and 
Alpine is using muslib-c.  I once built an Alpine Docker image by 
hand that built ldc, but it couldn't survive D version/Alpine Os 
updates.

Thank you so much for this tool!
