* Makefile.in: Use default rules when compiling cygrun.o.

* dcrt0.cc (host_dependent_constants::init): Limit non-NT platforms to 32K
chunks when copying regions during a fork.
* path.cc (symlink_check_one): Add temporary debugging output.  Simplify
PATH_EXEC test.
* syscalls.cc (stat_suffixes): Null terminate this list.
