_pinfo::dup_proc_pipe: DuplicateHandle failed


Yesterday I reopened a project from 3 years ago.  Its makefiles allowed
me to build the code for an embedded project and the tools for
communicating from a PC to the microcontroller.  The embedded code is
68HC11 assembly code for Metrowerks CodeWarrior and the communication
tools are C++ for Borland C++.

The makefiles needed some minor tweaking (notably changing "\" to "\\"
in some paths), which isn't a problem.  However, running "make -f
makefile.gnu" also produces errors of form:

  8 [main] bash 4988! _pinfo::dup_proc_pipe: DuplicateHandle failed, 
  pid 4988, hProcess 0x68D, wr_proc_pipe 0x750, Win32 error 6

I've got cygwin-1.5.25-11, make-3.81-2, and bash 3.2.33-18 installed.  I
presume these have all been updated since I last built the project in
2005. Reading the mailing list archives I've seen several reports of
"dup_proc_pipe DuplicateHandle failed" but don't see any indications of
workarounds or fixes.

Does anybody have a workaround or a fix???
