I see that glibc also defines struct iphdr in netinet/ip.h, so why doesn't it also suffer from this? I find it really strange that this, therefore, only happens for musl and we haven't had thousands of reports of this conflict with glibc over the years. I want an explanation, and suitably appropriate adjustments to the commit message and comments of this change. Thank you.
