I didn't miss it. I just did it another way. The dll.c module is
included in the build but the entire content of dll.c is skipped when
building the static library. I thought it would be better to excise the
code itself. Is that causing a problem for you?

It should be safe to call phread_win32_thread_detach_np() even if no
POSIX routines have been called. For instance, I imagine, since you're
project is a dll, you could call these attach/detach routines from your
own dllMain switch.
