[ID 20010305.008] lib/1_compile and lib/dosglob fail in maketest, but not when harnesed

This is a bug report for perl from dcd@tc.fluke.com,
generated with the help of perlbug 1.33 running under perl v5.7.0.

When executing make test I get the following failures

lib/1_compile.........FAILED at test 13
lib/dosglob...........FAILED at test 10

If I run these 2 tests directly from harness they don't fail

dd:t$ ./perl -I../lib harness lib/1_compile.t lib/dosglob.t
lib/1_compile.......ok                                                       
lib/dosglob.........ok                                                       
All tests successful.
Files=2, Tests=147, 13 wallclock secs (11.80 cusr +  1.16 csys = 12.96 CPU)


If I run the whole test suite, the above tests still pass
dd:t$ ./perl -I../lib harness

./perl TEST </dev/tty;    # (same as ./perl TEST )
lib/1_compile.........FAILED at test 8
lib/dosglob...........FAILED at test 10
lib/ipc_sysv..........FAILED at test 0

./perl -I../lib TEST  lib/1_compile.t lib/dosglob.t lib/ipc_sysv.t
lib/1_compile...FAILED at test 8
lib/dosglob.....FAILED at test 10
lib/ipc_sysv....FAILED at test 0



I am puzzled as to why lib/1_compile fails on make test at
step 13 on make test, but at test 8 when executed as ./perl TEST </dev/tty;
 (this is repeatable)

Also strange is why lib/ipc_sysv doesn't fail under make test, but
only under ./perl TEST </dev/tty;
 (this too is repeatable)


---
For one last test I modified t/TEST to set @ARGV to
  @ARGV = qw(lib/1_compile.t lib/dosglob.t lib/ipc_sysv.t)

and reran make test  and the stand alone 'equivalent' and
still get the different results. (note how 1_compile still
fails at test 13 instead of test 8, and ipc_sysv passes
under make test. 

.....
cd t && (rm -f perl; /bin/ln -s ../perl perl)
if (true </dev/tty) >/dev/null 2>&1; then \
  cd t &&  ./perl TEST </dev/tty; \
else \
  cd t && PERL_SKIP_TTY_TEST=1  ./perl TEST; \
fi
