cad/stepccode fails on -CURRENT since clang-6.0.0 was imported

[Fernando Apesteguía]

Hi there,

Since clang-6.0.0 was imported in -CURRENT
(https://svnweb.freebsd.org/base/head/usr.bin/clang/llvm-cov/?view=log),
cad/stepcode fails to build. It built fine in -CURRENT with
clang-5.0.0 on both i386 and amd64.

The full log can be found here (although I can't acces theat URL
anymore, how long do they last?):

Log URL:
http://beefy11.nyi.freebsd.org/data/head-i386-default/p459899_s328300/logs/stepcode-0.8_3.log
Build URL:
http://beefy11.nyi.freebsd.org/build.html?mastername=head-i386-default&build=p459899_s328300

Last lines of the error log are as follows:

I have no idea what the reason for the fail is. I had a look at the
change log from 5 to 6 but a lot of things have gone on and I can not
find any specific commit to blame.

Sorry for the delay reporting this, but I didn't have time to have a
look until a couple of days ago.

Can anyone help here?

Thanks in advance.
