ExtUtils-CBuilder 0.16

on Perl CPAN

Fix quoting of command line arguments on Windows. [Yitzchak
Scott-Thoennes]

Provided a custom arg_defines() on VMS that does essentially the
same thing for /define that version 0.14 did for /include. [Craig
A. Berry]

Documented the existing 'quiet' parameter, which silences the
printing of system() commands. [Suggested by Yitzchak
