Support for C++ extension in UNIX builds

Add PHP_REQUIRE_CXX to your config.m4

I've written a PHP5 extension in C++ that builds great on Linux with GCC, whether I compile it
into PHP or build it as a shared library.

On Solaris with Sun CC, however, I've had to manually edit the Makefile or the libtool script in
order to successfully build my extension. When I compile the extension into PHP, I have to change
$(CC) to $(CXX) in certain places in the Makefile. When I build it as a dynamic library, I have to
edit libtool so that it uses $(CXX) and not ld to create the shared library.

Am I overlooking some configuration step that eliminates the need to manually edit these files?

Thanks,

*.cpp files are automatically compiled using $(CXX).  Make
sure that you use the sanctioned suffix.

When I build it as a dynamic library, I have to edit libtool so
that it uses $(CXX) and not ld to create the shared library.

libtool 1.4 does not support building DSOs in a portable way
for any language but C.  Try libtool 1.5.

fwiw, I've never had these problems with gcc's C++ compiler on Solaris when
building C++ extensions, and the final linking step is usually done by gcc,
not g++. When you do the linking, do you link to the stdc++ library?
