osstest switched from using Debian 7.0 (Wheezy) to Debian 8 (Jessie) as the
base distro, which will have update the compiler etc.

I can't see why this would cause this kind of issue though, but I'm
somewhat hampered by the line numbers not matching and the amount of
ifdeffery in this auto generated file.

Since 4.5 looks ok perhaps one of the below is needed? In fact, yes, I'm
sure, since in the logs I now see:

/usr/bin/bison --output=libxlu_cfg_y.c libxlu_cfg_y.y
python gentypes.py libxl_types_internal.idl __libxl_types_internal.h 
__libxl_types_internal_json.h __libxl_types_internal.c
libxlu_cfg_y.y:34.1-13: warning: deprecated directive, use '%name-prefix' 
[-Wdeprecated]
Â%name-prefix="xlu__cfg_yy"
Â^^^^^^^^^^^^^

which matches some of the keywords in 7ba4cdfadd4f3's commit message...

commit 7ba4cdfadd4f3c45d65ffe50e621759f458fedc0
Author: Ed Swierk <eswierk@xxxxxxxxxxxxxxxxxx>
Date:ÂÂÂTue Jan 6 15:21:07 2015 +0000

ÂÂÂÂlibxl: Fix building libxlu_cfg_y.y with bison 3.0
ÂÂÂÂ
ÂÂÂÂ- Use %lex-param instead of obsolete YYLEX_PARAM to override lex scanner
ÂÂÂÂÂÂparameter
ÂÂÂÂ- Change deprecated %name-prefix= to %name-prefix
ÂÂÂÂ
ÂÂÂÂTested against bison 2.4.1 and 3.0.2.
ÂÂÂÂ
ÂÂÂÂThis is expected to sometimes (depending on timestamps and whether the
ÂÂÂÂbison input files are edited) break building on systems with ancient
ÂÂÂÂversions of bison.ÂÂBison 2.4.1 is known to work and was released in
ÂÂÂÂDecember 2008.
ÂÂÂÂ
ÂÂÂÂAlso, consquentially, regenerate bison output files with bison
ÂÂÂÂ1:2.5.dfsg-2.1 from Debian wheezy.

commit dc92f1a781a160229e4935dc03040bc78712a828

ÂÂÂÂlibxl: Rerun bison
ÂÂÂÂ
ÂÂÂÂThis updates libxlu_cfg_y.[ch] to code generated by bison from
ÂÂÂÂDebian wheezy (1:2.5.dfsg-2.1 i386).
ÂÂÂÂ
ÂÂÂÂThere should be no functional change since there is no change to the
ÂÂÂÂsource file, but we will inherit bugfixes and behavioural changes from
ÂÂÂÂthe new version of bison.ÂÂSo this is more a matter of hope than
ÂÂÂÂknowledge.
