# Apply a hack that Rick Felker suggested[1] to avoid conflicts between libc
|
|
# headers and kernel headers. This is needed for kernel headers older than
|
|
# 4.15. Kernel headers 4.15 and newer don't require __GLIBC__ to be defined.

# Augment the original suggestion with __USE_MISC since recent kernels
|
|
# (older than 4.15) require this glibc internal macro. Also, as musl defines
|
|
# IFF_LOWER_UP, IFF_DORMANT and IFF_ECHO, add another macro to suppress
|
|
# them in the kernel header, and avoid macro/enum conflict.

# Kernel version 3.12 introduced the libc-compat.h header.
