New Revision: 151935

URL: http://llvm.org/viewvc/llvm-project?rev=151935&view=rev
Log:
Fix an ABI problem with ptrdiff_t and intptr_t on PPC32

ptrdiff_t on PPC32 on Linux, etc. should be int not long.
This does not matter for C, but it does matter for C++ because of
name mangling.

The preprocessor test has been changed accordingly.
