The d_type field, and the corresponding macros such as DT_REG, are not
portable.

The only portable field in the dirent structure is d_name.

If you want to be really really super portable, you have to think
about supporting direct.h and other header files.  See AC_DIR_HEADER
and AC_HEADER_DIRENT in the autoconf documentation.  But these days
probably every OS of interest supports dirent.h, which is defined by
POSIX.
