* src/libs/libgroff/searchpath.cpp (is_directory): New function uses stat(2) to check file name argument to see if it's a directory, and returns a Boolean. (search_path::open_file): (search_path::open_file_cautious): Use `is_directory()` before attempting to `fopen()` a file specification; fail and set `errno` to `EISDIR` if it's a directory so that the caller reports a useful diagnostic. * bootstrap.conf: Add gnulib `stat` module, because the story of POSIX and non-POSIX systems alike trying and failing to sensibly implement the fundamental Unix file system model is a sorry tale of indifference and self-owns by rock star programmers. (Seriously, read the "sys/stat.h" and "stat" sections of the gnulib manual.) Fixes <https://savannah.gnu.org/bugs/?65980>. Thanks to Dave Kemper for the report.
