DDD does not compile with GCC 3.2.2

[abionnnn]

Hi I'm a huge fan of your program, but gcc-3.2.2 would not compile it. 
My gcc version is:

bash-2.05b$ gcc -v
Reading specs from /usr/lib/gcc-lib/i386-slackware-linux/3.2.2/specs
Configured with: ../gcc-3.2.2/configure --prefix=/usr --enable-shared 
--enable-threads=posix --enable-__cxa_atexit --disable-checking 
--with-gnu-ld --verbose --target=i386-slackware-linux 
--host=i386-slackware-linux
Thread model: posix
gcc version 3.2.2

The place where the compiler croaks is here:

For the record I'm using Slackware 9.0. Anyway thanks again for your 
hard work!
