03e44d4aa0 CheckMemoryLeakInFunction: Don't treat delete as delete operator for C code

98e33a189f Enhanced CheckBufferOverrun: 
- Fixed bug in library: manual and existing libraries use "size", but library.cpp reads "sizeof" as podtype attribute
- Fixed a couple of bugs in handling unknown size in checkbufferoverrun.cpp, get size from library if available.
