[sigc] Unable to build libsigc++ 2.0.10

[Jacob Mandelson <gnome jlm ofb net>]

Hello,

   When I attempt to build libsigc++ 2.0.10, I get errors in lambda.cc:
   g++ -DHAVE_CONFIG_H -I.. -I.. -g -O2 -MT lambda.lo -MD -MP -MF .deps/lambda.Tpo -c adaptors/lambda/lambda.cc  -fPIC -DPIC -o .libs/lambda.o

And so on and so on.
I've tried the prior versions, 2.0.9 and 2.0.8, but these give the same errors.
This is with g++ 3.2.2 on Linux 2.4.22.
Anyone know what's going on?
