Description:
------------
When embedding the crack extension statically into PHP, build fails with an error in ext/crack/libcrack/src/cracklib.h.

Compiling as a module works fine.

Reproduce code:
---------------
$ tar xzf php-5.0.5.tar.gz
$ cd php-5.0.5
$ cd ext
$ tar xzf crack-0.4.tgz
$ mv crack-0.4 crack
$ rm -f package.xml package2.xml
$ cd ..
$ rm -f configure
$ ./buildconf --force
Forcing buildconf

buildconf: autoconf version 2.13 (ok)

$ ./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var \

Thank you for using PHP.
