Error compiling backhand 1.2.2 on Solaris 2.9

Hi there,

I have a problem compiling mod_backhand/1.2.2 with Apache/1.3.27 on 
Solaris 2.9 (SPARC) with gcc 3.2.2:

After precompile I invoke the Apache configure like this:
./configure --enable-module=so --enable-module=backhand --enable-
shared=backhand --enable-module=status --enable-shared=status --
enable-module=info --enable-shared=info --prefix=/opt/apache-1.3.27 
--enable-rule=SHARED_CORE

(Last rule because of older messages in this list but its absence 
doesn´t change anything.)

And I get:

-- snip --

It works however, if I use mod_backhand/1.2.1 instead:

Warnings are still there, but no error.

Any suggestions?
