My error is different.

The problem seems to be that libgeos.la does not specify -lstdc++ as a
dependency_lib, and the capi test is linked with cc, not c++, so that
standard C++ library isn't linked.

Changing to using c++ instead of cc on that test makes it link, but I'm
not clear on what's right.


A basic question is if we expect linking with the geos C library to be
doable in an invocation of the C compiler (as linker) that does not
include -lstdc++.  I would think so, but I need to look further into how
this is supposed to work.
