Nick, do you plan to update your change? I think it is a good starting point. I
would propose to do not allow these options to be available on non-PE targets

Ah, flag 0x0002 has not only two differet names IMAGE_SCN_MEM_16BIT and
IMAGE_SCN_MEM_PURGEABLE, but also two different meanings. For

Ou, now I see that IMAGE_SCN_GPREL is alias for IMAGE_SCN_MEM_FARDATA and
IMAGE_SCN_MEM_16BIT alias for IMAGE_SCN_MEM_PURGEABLE. And these twos are

And IMAGE_SCN_TYPE_DSECT is

Thank you. I have looked at the change and from documented IMAGE_SCN_* flags at
https://learn.microsoft.com/en-us/windows/win32/debug/pe-format and for dumping

IMAGE_SCN_MEM_WRITE characteristic is added only when readonly flag is not

Ok, I have tested objcopy --set-section-flags on PE executable. Seems that it
is doing something, but only for some of the flags and I really do not
understand what it is doing. For me it looks like that objc
