[sigc] 2.0.0-2.0.2 fail to build on AMD64

["Robert J. Hansen" <rjh sixdemonbag org>]

Subject should say it all.  After doing a vanilla configure, Make
crashes with the following:

Google says this is a bug in a lot of existing configure scripts, and
that a workaround can be found just by regenerating the configure script
from aclocal/autoconf.  After doing a make clean and regenerating the
configure script, I get the following:

I've verified this for 2.0.0 through 2.0.2.  Anyone have any suggestions
for how to get it to make on AMD64?
