Description:
------------
starting at commit ddb6d7801e5dfc2f196b549b8ad51376cdc1bc90, PHP fails to compile on OSX. 



Test script:
---------------
make clean

./buildconf --force

# configure phpng
env YACC=`brew --prefix bison27`/bin/bison 
./configure \
    --prefix="/usr/local/opt/phpng" \
    --with-config-file-path="/usr/local/etc/phpng" \
    --with-config-file-scan-dir=/usr/local/etc/phpng/conf.d \
    --enable-mbstring \
    --enable-tokenizer \
    --with-curl \
    --with-sqlite3 \
    --enable-json \
    --disable-all
make -j`sysctl -n hw.logicalcpu_max`


Expected result:

Have you tried to manually rebuild the language parsers? It seems like ddb6d7801e5dfc2f196b549b8ad51376cdc1bc90 only updated the grammar file, but didn't actually regenerate the parsers, but I could be mistaken.

Cc'ing Nikita for this one

Hi

I don't know how to 'rebuild the language parsers', so I checked out a clean php-src, and used the command below : it works.

I'm interested in the extra command to rebuild the language parser.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php

Hi

I'm not sure how it is done on non-Windows, but from our makefile on Windows, we do:

bison --output=Zend/zend_language_parser.c -v -d -p zend Zend/zend_language_parser.y

So I guess it would be sort of similar for Unix. You can maybe find something in one of the makefile files to help, our Windows definitions are found in win32/build/makefile.

Hope it helps!

Actually, calling `./genfiles` fixes the issue for me.
