Ubuntu dmd 2.065 amd64 linkage problem.

[Carl Sturtivant]

Back at 2.062 I was able to force the whole of D's runtime/phobos 
into an executable which was exactly what I wanted for a specific 
project containing not just D but around 50,000 lines of C. (This 
is to do with having dynamic libraries link back to the 
executable when they're loaded with dlopen, so they don't need 
their own runtime/phobos on board.) However, at 2.065 this 
doesn't happen any more. I need this same linkage with 2.065. 
Previously I used

    -Wl,--whole-archive -lphobos2 -Wl,--no-whole-archive

on a gcc command line to link all the objects in the project 
along with libphobos2, with

    -lcurl -lpthread -lm -lrt

to satisfy that linkage, and this had the desired effect. But now 
this doesn't do the job of linking the whole of D's runtime & 
phobos any more. Any suggestions how I can get the old result 
with 2.065?
