From d429a873fa0b6c1c071c486ba18e5dc7a73a1bb3 Mon Sep 17 00:00:00 2001

Subject: [PATCH] [project @ 2004-11-06 16:34:25 by panne] 'd->d_name' (where
 d is of type 'struct dirent*') should always return a
 pointer to the directory entry's name, regardless if dirent
 is defined as

    struct dirent { ... ; char d_name[...]; }

or

    struct dirent { ... ; char* d_name; }

No need for autoconf trickery here.
