Invalid command ld -shared if build using GCC 4.x

Description
There is a known bug in libgeotiff ./configure script which has been well documented in various places, two of them:
- libgeotiff lesson for today on XASTIR project Wiki
- Work around a bug in libgeotiff's configure script on Ubuntu
The problem is that geotiff's configure script will tell the Makefile to run "ld -shared" to build a shared library, and that's not correct with GCC versions 4 and up. This results in a shared library that does not properly include all the references to other shared libraries it's supposed to have. The correct way to build a shared library using gcc 4.x is to use "gcc -shared" instead.
I can confirm this problem occurs on Ubuntu 8.10.

Frank,
I'm testing current SVN trunk (r1649) on my Ubuntu 9.04 and here is what I'm getting:
mloskot@dog:~/dev/libgeotiff/_svn/trunk$ ./autogen.sh Running automake aclocal.m4:14: error: this file was generated for autoconf 2.61. You have another version of autoconf. If you want to use that, you should regenerate the build system entirely. aclocal.m4:14: the top level autom4te: /usr/bin/m4 failed with exit status: 63 automake: autoconf failed with exit status: 63 Running autoconf aclocal.m4:14: error: this file was generated for autoconf 2.61. You have another version of autoconf. If you want to use that, you should regenerate the build system entirely. aclocal.m4:14: the top level autom4te: /usr/bin/m4 failed with exit status: 63 Something went wrong, giving up! mloskot@dog:~/dev/libgeotiff/_svn/trunk$
I've noticed that ./autogen.sh is somewhat incomplete, so I cleaned my copy of the source tree and copied autogen.sh from libLAS (also attached), removed -I m4 option and now everything works:
- generate ./configure

Fixed version of ./autogen.sh based on the script copied from libLAS project

I have restored hobu's original autogen.sh with some extra logic to preserve geo_config.h.in which I do not want to be autogenerated (r1650).

In SVN Howard has reworked things to use libtool. Would you like to check if this resolves this particular issue?
