For glibc.  On cygwin, it looks like all the argz_ functions were added at 
once, on 2002-06-14.  But does this properly test for bugs in the argz_ 
implementation?  For example, cygwin argz_add_sep failed to handle empty string 
arguments as recently as 2007-05-29.  Libtool has already faced hurdles 
detecting cygwin brokenness in the subset of argz_ that libltdl uses; and now 
that we are expanding the set of functions, we should be sure that the .m4 file 
catches all of cygwin's previous bugs, and not just the ones tickled by libltdl.
