Re: [wdiff-bugs] wdiff-0.6.1 build problems

Hi there!

Nelson H. F. Beebe reports problems building Gnulib sources shipped with
wdiff 0.6.1. Those sources should be up to date, so current git should
exhibit these problems as well.

 I did a fresh build using gcc-2.95.3 (the last gcc version that builds
 on that O/S), and that solved the problem.

Can you imagine what's causing this?
Do you have an idea how to avoid this?
Do you want to address this even if a gcc update solves the issue?
I've asked Nelson for additional information, config.{log,status} in
particular, so maybe we can provide more details soon.

Hi Martin,

  On Solaris 7 SPARC, compilation with cc fails like this:

Thanks for the forward, this problem is in gnulib's area.

 Can you imagine what's causing this?

It relates to the use of include_next. m4/include_next.m4 contains a number
of compiler dependent workarounds. Maybe one more such workaround is needed?
