bug#637: 23.0.60; configure using faulty defaults, causing failure to build temacs?

[Peter Dyballa]

Hello!

I tried to find out how it comes that Mac OS X framworks are getting  
used. They are introduced from Fink's libotf.pc and freetype2.pc.  
Resetting PKG_CONFIG_PATH I could avoid using the two PC files.  
Temacs was built:

	gcc -I/sw/include -L/sw/lib -prebind -Xlinker -headerpad -Xlinker  
690 -multiply_defined suppress -L/sw/lib/ncurses -L/sw/lib -L/usr/

lintl -liconv -L/sw/lib -ldbus-1 -lresolv -lncurses

(and also in another try without -L/sw/lib/fontconfig2/lib).

Temacs died both times with:

        cd ../lisp; make -k update-subdirs
	wd=.../emacs/lisp; subdirs=`(cd $wd; find . -type d -print)`; for  
file in $subdirs; do case $file in */Old | */RCS | */CVS | */CVS/* |  
*/.* | */.*/* | */=* ) ;; *) wins="$wins $wd/$file" ;; esac; done; \
        for file in $wins; do \
           .../emacs/lisp/../update-subdirs $file; \
        done;
        `/bin/pwd`/temacs --batch --load loadup bootstrap
        make[1]: *** [bootstrap-emacs] Bus error
        make[1]: Target `all' not remade because of errors.
        make: *** [src] Error 2
        make: Target `all' not remade because of errors.

I loaded temacs into gdb, set its arguments to '-batch --load loadup  
bootstrap' and let it run:

Starting program: .../emacs/src/temacs --batch --load loadup bootstrap

Program received signal EXC_BAD_ACCESS, Could not access memory.

Xbacktrace just brings the GDB prompt. I'll try without optimisation  
(-O0) again!
