kbd uses _Generic since version 2.2.90 and
https://github.com/legionus/kbd/commit/da5feb8fd90c3a0df9d505d4604c629d051d3d7d
However, _Generic is not available until gcc 4.9:
https://gcc.gnu.org/wiki/C11Status
As a result, build with gcc 4.8 fails on:
setleds.c:352:3: warning: implicit declaration of function '_Generic' [-Wimplicit-function-declaration]
ndefflags = BITMASK_SET(BITMASK_UNSET(odefflags, ndef), nval);
^
setleds.c:22:2: error: expected expression before 'unsigned'
unsigned char: (unsigned char)(~(x)) \
^
