Possible a bug of libtool?

[James Su]

Hi,
I'm developing a library with C++ language, and use
libtool/automake/autoconf to speedup my development work. But, when I
switched to gcc-3.2, a problem occurred. My library did not be linked
with C++ library anymore. I digged into the make process and noticed
that, at the link stage, a command like "libtool --mode=link g++ -o
libxxx.la ..." was invoked, but gcc was called to link my library,
rather than g++! Is it a bug of libtool?
I'm using libtool-1.4.3 and autoconf 2.53/automake 1.63.
