Thanks for tracking these down. See below:

> arch/arm/src/__aeabi_atexit.c

This ia an ABI function but has no public declaration and is not
callable as API.

> src/internal/procfdname.c

This is an internal function.

Should be fixed to include unistd.h.

Internal.

> src/signal/sigrtmin.c

ABI but the symbol is exposed via a public macro in signal.h so I
think we should include the header.

Definitely should include header.

> src/time/__month_to_secs.c
> src/time/__year_to_secs.c

Internal.
