[sigc] test_lambda in 2.0.5 fails to compile with gcc 3.4.2

[Jeff Franks <jcf tpg com au>]

Hi,

test_lambda in 2.0.5 fails to compile with gcc 3.4.2 on fedora 3 test2, 
producing the following errors:

if g++  -I. -I. -I.. -I.. -I..    -g -O2 -MT test_lambda.o -MD -MP -MF 
".deps/test_lambda.Tpo" -c -o test_lambda.o test_lambda.cc; \
then mv -f ".deps/test_lambda.Tpo" ".deps/test_lambda.Po"; else rm -f 
".deps/test_lambda.Tpo"; exit 1; fi
