Problem with custom accounting module.

[Bill Schoolfield]

Basically we took rlm_detail and extended it. In other words we first 
try to put the data to our application. If that fails then we fall back 
on the normal detail processing.

The library we call is not thread safe so we "marked" our module 
accordingly.

Since my last post I got it to work by re-ordering the link options. 
However I just tried to repeat this build on yet another box and it 
fails again.

The dependencies in our library are long but not really unusual. Here is 
what worked:

-lfreeradius-radius -L/usr/local/billmax/lib 
-Wl,-rpath=/usr/local/billmax/lib -lbillmax -lxml2 -ldecNumber 
-L/usr/lib/mysql -lmysqlclient -lc
