Something I noticed in the original message:

/usr/local/arm-wince-pe/EntryPoint/Console/crt0.o(.text+0x2c): undefined 
reference to `main'

Looking at the nm output, all global symbols a prefixed with an 
underscore.  It looks like the main in crt0.o doesn't have an underscore 
(I don't think GNU ld removes prefixes for error messages.)  That might 
be the problem.  Does the gcc built along with gdc have the same 
problem?  Where does EntryPoint/Console/crt0.o come from?
