What could I do wrong by just using SimpleDllMain and then put my
exports?
build line for DLL is: rdmd -shared --build-only -gf -m64
Under Linux everything is shared. Under Windows each DLL seems to
run in its own thread, has its own rt_options and do not see any
__gshared variable value. Its completely isolated and so I assume
that also GC is.
Also https://wiki.dlang.org/Win32_DLLs_in_D says: Each EXE and
DLL will have their own gc instance.
I also wonder why the static linked DLL should use a GC proxy
while as SimpleDllMain does nothing with a proxy - should
loadLibrary() take care off here automatically? It seems, it does
not.
