I just wanted to let you know that in case you couldn't get a 
build on your host PC, there may be another way to get a GDC ARM 
Cortex-M cross-compiler.

It has come to my attention that the prebuilt binaries at 
http://gdcproject.org/downloads are capable of creating ARM 
Cortex-M binaries.  I just tested it myself.

I used the arm-linux-gnueabihf build, and the command I used for 
my STM32F4 (ARM Cortex-M4F) was:
arm-gdcproject-linux-gnueabi-gdc -fno-emit-moduleinfo -frelease 
-mthumb -mcpu=cortex-m4 -fdata-sections -ffunction-sections -c 
start.d

The key is to simply add the platform flags: -mthumb 
-mcpu=cortex-m4

I hope that helps.
