* dcrt0.cc (insert_file): Avoid freeing previously allocated argument list.

Browse Source 
* path.cc (symlink_info::check): Rename from symlink_check_one.  Use new
symlink_info struct for communication.
(path_conv::path_conv): Use symlink_info structure for communication with
symlink_info::check.  Fix typo which resulted in symbolic links always being
resolved.
(readlink): Use stat_suffixes array when resolving a link.
* syscalls.cc (stat_suffixes): Make global.
