Re: Problems with directory trees "confdir-14B---" and "confdir3"

[Peter Dyballa]

Hello!

I managed to set up "my" configure to run quite similar to that in  
MacPorts. Differences are (MacPorts vs. me):

        checking whether getcwd aborts when 4k < cwd_length < 16k... no

vs.

        checking whether getcwd aborts when 4k < cwd_length < 16k... yes

and of course the reports about not being able to remove the  
"confdir-14B---" and "confdir3" directory trees, i n MacPorts. Looking  
into the config.log files I see (MacPorts vs. me):

	configure:26149: checking whether getcwd aborts when 4k < cwd_length  
< 16k
	configure:26285: /usr/bin/gcc-4.2 -std=gnu99 -o conftest -pipe -Os - 
arch ppc -I/opt/local/include -L/opt/local/lib -Wl,- 
headerpad_max_install_names -arch ppc conftest.c  >&5
        configure:26285: $? = 0
        configure:26285: ./conftest
        configure:26285: $? = 0
        configure:26302: result: no
        configure:26539: checking for flockfile
        
vs.

        configure:26302: result: yes
        configure:26539: checking for flockfile

Finally configure states (MacPorts vs. me):

        gl_cv_func_getcwd_abort_bug=no
        […]
        REPLACE_GETCWD='0'

vs.

        gl_cv_func_getcwd_abort_bug=yes
        […]
        REPLACE_GETCWD='1'

so that my configure includes 'getcwd.o getcwd-lgpl.o' to gl_LIBOBJS  
and 'getcwd.lo getcwd-lgpl.lo' to gl_LTLIBOBJS.

The config.log files are saved and also the configure output.
