Subject: fix compile errors on readdir()-deficient platforms
X-Git-Tag: v1.4.0-rc1~226
X-Git-Url: http://git.pk910.de/?p=srvx.git;a=commitdiff_plain;h=f8dd4fc662c0a192f777bc426b37336300670b9b

fix compile errors on readdir()-deficient platforms

* Cygwin does not have "struct dirent.d_type".  Check for that in the
configure script and use stat() to test for directory-ness instead.
