I took the chance to run the two builds I mentioned in my above linked
list-email once again.

GDALmake.opt is identical in both working and breaking version.

Excerpt:

SHELL    =   /bin/sh
LIBTOOL	=	$(SHELL) $(top_builddir)/libtool
LIBTOOL_COMPILE_CC =	$(LIBTOOL) --mode=compile --tag=CC
LIBTOOL_COMPILE_CXX =	$(LIBTOOL) --mode=compile --tag=CXX
CC	=	$(LIBTOOL_COMPILE_CC) gcc
CXX	=	$(LIBTOOL_COMPILE_CXX) g++

The only difference (for working and breaking) after running

$ ./configure --prefix=/usr/local --with-python

is within config.log and config.status.


Cheers,
Kai
