Current SVN doesn't build in Cygwin.
Created attachment 827 Fixes build and install This patch fixes the build (partially unfortunately, there is still an issue with setpassent() not being defined, I had to disable debug) More importandly, Win32 has no caps differenciation, and that patch addresses this (the link Thunar->thunar breaked the install)
Fixed with revision 23535. 2006-10-28 Benedikt Meurer <benny@xfce.org> * thunar-vfs/thunar-vfs-mime-cache.c(thunar_vfs_mime_cache_finalize): Fix compiler warning if mmap() is not available. * configure.in.in, thunar/Makefile.am: Do not install the symlink from thunar to Thunar on Win32 platforms. Bug #2432.
