On windows with dub it seems to be creating libfoo.a instead of foo.lib, I don't think I changed any settings. Old build based on 2.078 DMDFE seem to have built .lib but LDC based on 2.082 seems to be building .a
This definitely seems to be dubs fault: it passes -of/path/to/output/libFoo.a to LDC which compiles. `dub describe` also has
{
...
"packages" : [
...
{
...
"targetFileName" : "libFoo.a",
