This is a bug report for perl from khw@karl.(none),
generated with the help of perlbug 1.39 running under perl 5.17.4.


-----------------------------------------------------------------
Configure is not finding the C library routine isblank().
I see that it does something different from the portion that looks for
isascii(); when I change it to use the isascii() paradigm, it does find
isblank() on my machine.
