gnulib problem with getcwd when compiling octave

[Kai Habel]

I have reported the problem described below to the octave-maintainers list today. Is this a gnulib problem? It was confirmed for MSVC as well.

--------------------------------
I try to buid a very recent octave tip on mingw (32bit)
Today, I have updated gnulib as well ran into the following build problem:

I have used the following commands:
$ ./autogen.sh > LOG.conf 2>&1;./configure LDFLAGS="-L/usr/local/octmgw32/lib"
CPPFLAGS=-I/usr/local/octmgw32/include --disable-docs lt_cv_deplibs_check_metho
d='pass_all' GHOSTSCRIPT=gswin32.exe >> LOG.conf 2>&1;make > LOG 2>&1

after a while I got:

If I do

nm libgnu/.libs/libgnu.a | grep 'fdopendir'
       U _fdopendir

$ nm libgnu/.libs/libgnu.a | grep 'fstatat'
fstatat.o:
00000000 T _rpl_fstatat
         U _fstatat

it seems that fdopendir is not there. If look at the compile log for libgnu, I see fdopendir is not linked in but fstatat is.
