Subject: [PATCH] 	PR c++/13225 	* gdb.cp/converts.cc (foo3_1): New
 function. 	(foo3_2): New functions. 	* gdb.cp/converts.exp: Add
 tests for int to pointer conversion 	and null pointer conversions of
 integer constant zero. 	Add test to check if all arguments are checked
 for incompatible 	conversion BADNESS.
