configure doesn't test for yacc

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Don't install yacc/bison on your system
2. ./configure
3. make
4. Watch compile fail on missing yacc

This is on latest SVN.

Hi,
you are right; unfortunately it seems to be the default behavior of the macro I 
use (AC_PROG_YACC).
I'll try and add explicit check for bison...
Thank you for the report!
Kind regards,

Michal

PS. I found this:
If AC_PROG_YACC set YACC to 'bison -y', then 'bison' is on PATH.  Only
if $YACC ends up as 'yacc' do you run the risk that AC_PROG_YACC didn't
find anything.  But since 'yacc' is required to be on all POSIX-y
systems and is listed as one of the portable programs that the GNU
Coding Standards states that you can assume to exist, this shouldn't
matter in practice.

Weird, it's definitely not on Ubuntu by default and doesn't come in the 
build-essential package.

I know, I haven't found it in base packages either.
Anyway, I'm working on a explicit test for bison; will check it in when I get 
home.
Kind regards,

Michal

Hello,
I just checked-in the test for bison (rev798).
I'm going to close this issue now; should you run into this problem again, 
please reopen it or file a new one...
Thank you for your help,

Michal
