I don't think the problems I encountered with GDC were the fault 
of GDC.  They were my fault.  I have more to learn about the 
Linux platform.  It seems the GCC toolchain is highly dependent 
on the  host platform and if things aren't set up just right, you 
get errors that have nothing to do with the actual problem.

Also, when I tried to follow the crosstools instructions here 
(http://wiki.dlang.org/GDC/Cross_Compiler) I found that the 
latest crosstools was missing some of the options that are needed.

I have been quite successful using the GNU Tools for ARM Embedded 
Processors here (https://launchpad.net/gcc-arm-embedded), and I 
hope to merge this with the GDC code and give it another try.  I 
tried it this weekend, but I wasn't even able to get the shell 
scripts to run without errors.

And, I didn't JUST give up.  I worked on it all weekend, every 
weekend, for the past 3 weeks.  I'm tired of the platform 
dependencies, and I'm anxious to just get started.  Once I get 
more familiar with D and have some working code, I'll give GDC 
another try.
