Re: PATCH: __cxa_vec_delete* Changes


2003-11-03 Jeffrey D. Oldham <oldham@codesourcery.com>

	* libsupc++/vec.cc (__cxa_vec_delete2): If given a NULL pointer,
	immediately return.  This reflects a C++ ABI change 2003 Nov 03.
	(__cxa_vec_delete3): Likewise.

Tested on i686-pc-linux-gnu by running check-g++ with no regressions.
