Just me? Compiling chmgen head on DMD master vs 2.063.2

[Nick Sabalausky]

Can anyone see whether or not they're able to reproduce this, because
I'm not sure if it's some weird bug or just something wrong on my
system:

On windows, compiling the latest chmgen.d with DMD v2.063.2 works fine
("dmd chmgen.d"). But doing exactly the same with github master of
dmd/druntime/phobos results in several missing symbols during linking:
