Are you sure of that? I get exactly the same kind of linker error when 
forgetting a fake main(){} (whatver the number of modules). Eg:
	...
	src/rt/deh2.d:(.text._D2rt4deh213__eh_finddataFPvZPS2rt4deh213DHandlerTable+0xc): undefined reference to `_deh_beg'
	src/rt/deh2.d:(.text._D2rt4deh213__eh_finddataFPvZPS2rt4deh213DHandlerTable+0x13): undefined reference to `_deh_end'
	...
repeted n times.
