Author: pfg Date: Sun Jan 26 02:36:06 2014 New Revision: 261178 URL: http://svnweb.freebsd.org/changeset/base/261178 Log: gcc: Add support for -Wmissing-prototypes in C++ Support for warnings about missing prototypes in C++ was added by Apple GCC (Radar 6261539). Most of the code crept into r260311 so it felt natural to make use of it.
