I'm having a bit of trouble with this morning's code (Jan 11 09:20 UTC):

# sh build.sh -D /usr/export/amd64 -r -j1 release
...
dependall ===> tools/compat
#   compile  compat/atoll.lo
...
/usr/src/tools/compat/compat_defs.h: In function 'be16enc':
/usr/src/tools/compat/compat_defs.h:1138:25: error: implicit declaration of function 'bswap16' [-Wimplicit-function-declaration]
 1138 | #define htobe16(x)      bswap16((u_int16_t)(x))
      |                         ^~~~~~~

full log attached.

Thanks for looking at this!
