# "autoreconf -i" command was run on Linux to propagate these
# changes to the corresponding configure shell script. This could
# not be done for each platform since the autoreconf command is
# broken on MSYS. A final change in this patch is Makefile.in was
# edited to make it compatible with the itk version, and finally an
# additional edit was made to this file so that CPPFLAGS and CFLAGS
# take precedence over CONFIGS which contains the values derived
# from the tclConfig.sh, tkConfig.sh, and itclConfig.sh files.
# Without this final change the -I options come out in the wrong
# order so that the itcl4 version of headers is (incorrectly) used
# rather than the itcl3 version provided by CPPFLAGS.
