Good, thanks for confirming! Still, this would be a bit of an awkward

We can do that, but what to do about compiler-emitted __DATA,__const?

They are not, that is the whole point of the patch in its current shape.
.rodata is valid for ELF and Mach-O, PE/COFF needs .rdata.

I feel like I'm too tired to get the point. Do you mean you want
comments whenever this section name is used? Or comments in tools_def?
