# This target prepares the patch file
# after new patches have been applied/coded.
# It assumes that the new/patched files are in
# in 
#     doxygen-$(DOX_VER)
# and unpacks the unpatched code to make the diff
#     tmp_unpack/doxygen-$(DOX_VER).orig
#
# Does not use doxygen as directory name but adds .orig
# to make clearer reading the patch file.
# Before preparing the patch also cleans up the code with the patches
# Makes a copy of the previous patch file for comparison
# and deleted the unpatched code afterwards.
# 
# I had to put a 'true' because patch returns -1. No idea why.
