Build failure with version 2007-08-20

I decided to play around with the latest Gnucap snapshot,
gnucap-2007-08-20.  I did the usual "configure && make" incantation.
However, the build fails with this message:

if g++ -DHAVE_CONFIG_H -I. -I. -I.. -I../src  -DNDEBUG  -g -O2 -MT

mg_out_dev.cc; \
then mv -f ".deps/mg_out_dev.Tpo" ".deps/mg_out_dev.Po"; else rm -f
".deps/mg_out_dev.Tpo"; exit 1; fi

Any ideas what's wrong?  Here are some vital stats about my build
platform:

src/gnucap-2007-08-20> uname -a
Linux localhost 2.6.11.4-20a-default #1 Wed Mar 23 21:52:37 UTC 2005
i686 i686 i386 GNU/Linux

src/gnucap-2007-08-20> gcc --version
gcc (GCC) 3.3.5 20050117 (prerelease) (SUSE Linux)

The distro is SuSE 9.3.

TIA for any suggestions,
