dnl libltdl-supplied implementation (and default to do so

dnl on "known bad" systems). Could use a runtime check, but
|

dnl (a) detecting malloc issues is notoriously unreliable
|
|
dnl (b) only known system that declares argz functions,
|

dnl provides them, yet they are broken, is cygwin
|
|
dnl releases prior to 16-Mar-2007 (1.5.24 and earlier)

dnl So, it's more straightforward simply to special case
|
|
dnl this for known bad systems.
