It's hard to say what to do with some of these new symbols.  Could
you please clarify by answering the questions below?  I cannot advance
with fixing the Windows build until I understand what to do with them.

 . What is the semantics of the GNULIB_TEST_* macros?  The comments
   say "Define to 1 when the gnulib module FOO should be tested.", but
   what does it mean "should be tested"? tested by whom and at what
   time?

 . Why is NO_MINUS_C_MINUS_O needed?  Which compilation uses this
   macro?

 . Why are PACKAGE and VERSION needed, and where are they used?

TIA
