nullmailer-1.00 does not compile on FreeBSD-5.4

Hi,

Making all in cli++
if g++ -DHAVE_CONFIG_H -I. -I. -I../.. -I..     -g -O2 -fno-rtti -fno-exceptions
 -W -Wall -MT main.o -MD -MP -MF ".deps/main.Tpo" -c -o main.o main.cc;  then mv
 -f ".deps/main.Tpo" ".deps/main.Po"; else rm -f ".deps/main.Tpo"; exit 1; fi
if g++ -DHAVE_CONFIG_H -I. -I. -I../.. -I..     -g -O2 -fno-rtti -fno-exceptions
 -W -Wall -MT messages.o -MD -MP -MF ".deps/messages.Tpo" -c -o messages.o messa
ges.cc;  then mv -f ".deps/messages.Tpo" ".deps/messages.Po"; else rm -f ".deps/
messages.Tpo"; exit 1; fi
In file included from ../fdbuf/fdbuf.h:78,
                 from messages.cc:18:
../fdbuf/fdobuf.h:52: error: expected `;' before '(' token
