I think my patch posted last time is somewhat dirty.

I found the patch attached below also works and looks better.
I think lt_dlmalloc/lt_dlfree may well use malloc/free because
on a platform which has its own argz_* functions,  which seem
to be in glibc,  malloc/free seems to be used in argz_* functions.

Anyway,  I think this issue should be settled before the new release.
