Please try:
make distclean && ./configure --enable-linux-aio --enable-kvm
--enable-vhost-net && make

I tried that before I raised the bug. However I tried it again to be sure,
and yes I still get the same error.

Please post the output of "git status". I wonder if there are stale
files because the build works fine here.

Here it is:

# On branch master
# Untracked files:
# (use "git add <file>..." to include in what will be committed)
#
# libhw32/
# libhw64/
# trace.c
# trace.h

I don't do any local modification just 'git pull' and recompile. Perhaps
git is broken so I should 'git clone' and start again.

rm trace.[ch]

Then try again.

The problem is that the auto-generated tracing files moved into
trace/generated-* but the Makefile and C compiler include paths still
pick up the old trace.[ch].

You probably built an older version of QEMU first in the same
directory. The latest make distclean doesn't know about the old
trace.[ch] files.
