This fix relies on having the 'fchdir' function, and on having "." be searchable (or at least readable, on platforms lacking O_SEARCH), but that's good enough to handle the vast majority of cases and the remaining folks can just live with the annoyance of file systems that occasionally can't be unmounted. * configure.ac (fchdir): New function to check for. * lib/save-cwd.c: Copy from gnulib, except omit the part that allocates memory, since that can cause problems in Emacs. * lib/save-cwd.h: Copy from gnulib. Fixes: debbugs:18232
