Why is it necessary to port the djgpp routines anyway?  IIRC, all
systems have emulated findfirst already, except for Windows.

Now, struct _finddata_t from Mingw looks like this:

   struct _finddata_t
   {
        unsigned        attrib;         /* Attributes, see constants above. */
        time_t          time_create;
        time_t          time_access;    /* always midnight local time */
        time_t          time_write;
        _fsize_t        size;
        char            name[FILENAME_MAX];     /* may include spaces. */
   };

struct ffblk from Allegro (alconfig.h) looks like this:

   struct ffblk
   {
      unsigned char ff_attrib;
      unsigned short ff_ftime;
      unsigned short ff_fdate;
      unsigned long ff_fsize;
      char ff_name[1024];
      void *ff_info;
   };

It seems pretty simple to map struct _finddata_t to struct ffblk
(not sure about `ff_date'), and "_findfirst" to "findfirst".  The
issue is whether we really want to.

(I might have lost track of this thread, so apologies if I have.)
