See attached build.log for more context.

This commit may fix the problem, but it seems to be too new to apply to 3.8 without some work: https://github.com/yoe/nbd/commit/72d6ab0e7484d96608eb09242dae96020703fa57?diff=unified

$ emerge -pqv '=sys-block/nbd-3.8::gentoo'
[ebuild  N    ] sys-block/nbd-3.8  USE="zlib -debug"

that func is defined in the local header which is always included.  my guess is your system is screwed up.

to find out, go into the build dir and run:
x86_64-pc-linux-gnu-gcc -std=gnu99 -DHAVE_CONFIG_H -I.    -march=native -pipe \
 -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include  -march=native -pipe \
 -E -dD -o nbd_trdump-nbd-trdump.i nbd-trdump.c

then attach that .i file here
