configure thinks that my g++ does not support STL or ISO C++ standard library

[Jay F Shachter]

I don't assert that this is a gcc bug; it is more likely that I am
doing something wrong, and I hope that you can tell me how to fix it.

The ImageMagick "configure" script, as I indicated, thinks that my g++
does not support either the Standard Template Library, or the ISO C++
standard library.

Here is my output from gcc -v:

Reading specs from /gnu/lib/gcc-lib/sparc-sun-solaris2.7/3.0.3/specs

Here are the relevant excerpts from the configure output:

First, the STL test:

Second, the ISO test:

I went to ftp.gnu.org and retrieved the most recent version of
libstdc++ and determined that it was version 2.90.8; and for that
reason, I did not install it, because the version of libstdc++
currently on my system is version 3.0.2 (apparently libstdc++ is now
incorporated into gcc, and is no longer updated as a separate product).
Why is g++ generating the above compile-time errors, which lead
configure to conclude that I have neither STD nor ISO C++, and what
must I do to produce successful compilation of the test programs?
I thank you in advance for your reply.
