 I can reproduce that, but only on one out of a few update builds I did toda=
 y.
 I cleaned the objdir for sys/rump/net/lib/libwg and on this build it still
 happens.
 
 The "depends" phase gets it right, wg_user.d points at the correct assert.h
 header.
 
 Here is my compiler invocation:
 
 --- wg_user.go ---
 #   compile  libwg/wg_user.go
 /home/builds/current/tools/bin/sparc64--netbsd-gcc -O2  -fno-delete-null-po=
 inter-checks  -ffreestanding -fno-strict-aliasing   -std=3Dgnu11    -Wall -=

 Wswitch -Wshadow -Wcast-qual -Wwrite-strings -Wextra -Wno-unused-parameter =
 -Wno-sign-compare -Werror    -Wno-address-of-packed-member  -Wno-format-zer=
 o-length -Wno-pointer-sign   -fPIE     -I/home/martin/current/src/sys/rump/=

 nt/src/sys/rump/net/lib/libwg/wg_user.c -o wg_user.go
 
 
 and this is from wg_user.d:
 
 wg_user.o: /home/martin/current/src/sys/rump/net/lib/libwg/wg_user.c \
  /home/builds/current/dest/usr/include/sys/cdefs.h \
 [...]

  /home/builds/current/dest/usr/include/errno.h \
  /home/builds/current/dest/usr/include/sys/errno.h \
 [..]
 
 
 On the working builds I see (modulo the exact pathnames) the same in wg_use=
 r.d
 and the working compiler invocation e.g.:
 
 =66rom the depends phase:
 
 --- wg_user.d ---
 #    create  libwg/wg_user.d
 CC=3D/work/tools/bin/armv7eb--netbsdelf-eabihf-gcc /work/tools/bin/nbmkdep =
 -f wg_user.d --    -isysroot /work/branches/hosts-current/evbearmv7hf-eb  /=
 work/src/sys/rump/net/lib/libwg/wg_user.c
 
 
 and the real build:
 --- wg_user.o ---
 #   compile  libwg/wg_user.o
 /work/tools/bin/armv7eb--netbsdelf-eabihf-gcc -o wg_user.o -O2    -Wno-addr=
 ess-of-packed-member  -Wno-format-zero-length -Wno-pointer-sign    -Werror =
 -Wall -Wextra -Wno-unused-parameter -Wstrict-prototypes -Wmissing-prototype=
 s -isysroot /work/branches/hosts-current/evbearmv7hf-eb    -c /work/src/sys=
 /rump/net/lib/libwg/wg_user.c
 
 
 but the working builds do not try to build wg_user.go.
 
 So that made me discove I still have MKDEBUGLIB=3Dyes for this build, but r=
 emoved
 it (as it is basically never needed) from all the other builds some time
 ago.
