Probably this is harsh.
But look at this from end user's point of view - something used to work
and now it doesn't.
I think that monumental projects like 'bison' should have a regression
suite which includes major users of their code.
By the way, I'm building 'gcc' using my AppsFromScratch, and I'm also
building 'libIDL' in the same framework. I didn't try to build 'libIDL'
because 'gcc' failure was enough of show stopper for me, otherwise I would
have uncovered the 'libIDL' issue too.
AppsFromScratch happens to be a really good regression testing tool,
look, for example, at another recently reported regression issue:
http://lists.gnu.org/archive/html/bug-libtool/2008-11/msg00006.html
.
So, if you are interested,l I can send you a snapshot and explain how to
use it. I myself depend on the tool, so I have personal interest in
maintaining it.
My point is that even if 'gcc', 'libIDL', etc developers write erroneous
grammars, new 'bison' releases should be accompanied by release notes
notifying "big" users of problems uncovered in their code.
Thanks,
Sergei.
