# headers and kernel headers. This is a temporary measure until musl finds a

# better solution.

|
# Augment the original suggestion with __USE_MISC since recent kernels
|
# 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.
