The number of times that you typed:
sa_buf = close_on_exec ()
? sec_user_nih ((PSECURITY_ATTRIBUTES) char_sa_buf, cygheap->user.sid())
: sec_user ((PSECURITY_ATTRIBUTES) char_sa_buf, cygheap->user.sid());
implies that this should be a macro or a function.
Could the setting of close_on_exec be handled in the syscalls.cc open()
so that it doesn't have to be done so many times? You could have
build_fh_name set the noexec flag so that close_on_exec() would still
work in the fhandler_*::open functions.
