I copied the problem conftest code out of configure and created a
standalone program that reproduces the problem behavior each time
it's run.

After running, I attached gdb to the process and got this backtrace:

(gdb) bt
#0  0x77f9193d in ntdll!DbgUiConnectToDbg ()
   from /cygdrive/c/WINNT/system32/NTDLL.DLL
#1  0x7c57fe8d in KERNEL32!DebugActiveProcess ()
   from /cygdrive/c/WINNT/system32/KERNEL32.DLL
#2  0x61004409 in _cygtls::call2 () from /usr/bin/cygwin1.dll
#3  0x00000000 in ?? () from

I'm not really sure what this means.  If anyone's interested:

http://jca.sdf1.org/cygwin/conftest.c
http://jca.sdf1.org/cygwin/conftest.exe

Meanwhile, I found this thread related to screen 4.0.2 and the same
behavior:

http://sourceware.org/ml/cygwin/2005-06/msg00843.html

If I take the fifo test out of configure, the configure script completes
successfully.

I installed Andrew's test package which is working fine so far.
