Passing specific bison to build

Hi all,

I've upgraded to Fedora 19 and bison is too new for PHP 5.4/5.3
I would like to users to select specific bison to build with.

To build with specific bison, you may do

YACC=/usr/local/bin/bison1 ./configure

Any comments?

+1.

Would be very useful for RMing as well, as we have to test different bison
versions and use one for RMing which may not be the system's one.

Would you commit this patch from PHP 5.3?
It may be easier for us to maintain PHP 5.3 with this.

Thank you.
