Please describe the problem:
gdm compile dies during make.

This is on Slackware-12.0 with updates.

Steps to reproduce:
1. tar -xjvf gdm-2.20.3.tar.bz2
2. cd gdm-2.20.3
3. ./configure
4. make


Actual results:
The compile dies with:
verify-shadow.o: In function `gdm_verify_setup_user':
...
verify-shadow.c:435: undefined reference to `gdm_debug'

Expected results:
It compiles cleanly.

Does this happen every time?
Yes.

Other information:
Adding "#include gdm-log.h" to daemon/verify.h seems to allow it to compile.
