Just in case anyone wants another simple test case:

$ cat makefile
all:
        echo hi

$ make
echo hi
   7486 [main] make 2648 modify_handle: virtual void
fhandler_pipe::set_close_on_exec(bool):175 handle guard<0x734> not found
hi

$ uname -a
CYGWIN_NT-5.1 PC1163-8460-XP 1.7.0(0.160/4/2) 2006-08-17 08:07 i686
unknown unknown Cygwin

I'm looking at it as time permits, but I'm not optimistic I will decipher
enough to fix it :-(.  Note that running it under strace causes a hang
here:

$ strace -o junk make
echo hi

with make eating all the CPU.
