 Reported by Mark Rivers

 I have discovered a possibly related problem with stack overflow when
 calling Nexus API from a multi-threaded C program.  I found that the
 function NXgetgroupinfo uses a very large amout of stack.  I would get
 stack overflow when my thread had less than 40000 bytes of stack, it
 worked OK with 80000 bytes.  The stack overflow only happened for me on
 Windows with the MS VC++ compiler, it did not happen on Linux, or Windows
 with the gcc compiler.  But I suspect that NXgetgroupinfo is doing some
 recursion that can use a large amount of stack depending on the structure
 of the HDF file.
