Try to compile main_aux separately?
---
dmd -of=./build//app.o -c -g fun1.d fun2.d
dmd -of=./build//main.o -c -g main_aux.d
libtool -static ./build//app.o ./build//main.o -o ./build//libapp.a
dmd -of=./build//app -g -L./build//libapp.a main_aux.d

Usually linker can't omit symbols selectively from one object file, so you
should compile to separate object files, what dmd -lib does - that's why it
works.
btw what is // ?
