Hi Stefan, 

I think you have a PHP question.  Your setup looks reasonable to me. 

> [root at linux1 freetds-0.61]# ./configure --with-tdsver=8.0   
> --enable-dbmfix

OK, but --enable-dbmfix doesn't do anything anymore.  

> ./configure --with-apache=../apache_1.3.22 --enable-trans-sid 
> --with-sybase=/usr/local/freetds --with-openssl=../openssl-0.9.6 
> --with-mm=../mm-1.1.3 --enable-track-vars...

Looks good; you're using db-lib.

That's a little odd, because you don't define any servers, but OK.

I'm afraid I'm not going to be much help.  :-(

I'm sure if you look at the TDSDUMP log, you'll see the error message come
back from the server without any complaint from FreeTDS.  And if you use
tsql, you'll see the error message printed to the screen.  You could test
db-lib, too, by modifying a unit test (we don't have one specifically for
raiserror), but I wouldn't bother unless you're not confident that db-lib is
passing the message to PHP.  

The real question is, What is PHP doing with the message?  I don't use PHP,
so I don't know much about it, but ISTR there are a couple of ways to deal
with error messages, and some switches to set.  I can only suggest you look
in that direction, unless someone here can offer more concrete advice.
