Hi,

gnome-common did a cleanup upstream and deprecated quite a few macros
and variables.

gnome-doc-utils removal
=======================
The gnome-doc-utils build infrastructure was removed completely along
with the following macros:

 GNOME_DOC_INIT [1]
 GNOME_COMMON_INIT [2]


deprecated variables
====================
The following variables used in gnome-autogen.sh have been declared
deprecated [3]:

 REQUIRED_GNOME_DOC_UTILS_VERSION
 REQUIRED_DOC_COMMON_VERSION
 USE_COMMON_DOC_BUILD
 FORBIDDEN_M4MACROS
 GNOME2_DIR
 GNOME2_PATH
 USE_GNOME2_MACROS

deprecated macros
=================
The following macros have also been declared deprecated:

 GNOME_COMPILE_WARNINGS [4]
 GNOME_CXX_WARNINGS [5]

A "grep over the sources:"

./gthumb-3.4.3/configure:GNOME_COMMON_INIT
./gthumb-3.4.3/ChangeLog.pre-git:	USE_COMMON_DOC_BUILD=yes
./gthumb-3.4.3/aclocal.m4:dnl GNOME_COMPILE_WARNINGS
./gthumb-3.4.3/aclocal.m4:dnl For example:
GNOME_COMPILE_WARNINGS([maximum],[-Werror=some-flag -Wfoobar])
./gthumb-3.4.3/aclocal.m4:AU_DEFUN([GNOME_COMPILE_WARNINGS],[
./gthumb-3.4.3/aclocal.m4:AU_DEFUN([GNOME_CXX_WARNINGS],[
./gthumb-3.4.3/configure.ac:GNOME_COMMON_INIT
./gthumb-3.4.3/configure.ac:GNOME_COMPILE_WARNINGS([maximum])
./gthumb-3.4.3/configure.ac:GNOME_CXX_WARNINGS
./gthumb-3.4.3/extensions/example/autogen.sh:USE_GNOME2_MACROS=1
USE_COMMON_DOC_BUILD=yes . gnome-autogen.sh
./gthumb-3.4.3/extensions/example/configure.ac.example:GNOME_COMMON_INIT
./gthumb-3.4.3/extensions/example/configure.ac.example:GNOME_DOC_INIT
