Compiler Error
Description
The following testcase fails to compile because both the C library stdint.h and our tr1/cstdint headers define defines the C99 limit macros. It looks like we need to avoid defining the macros if a previous definition already exists. Is that a sufficient solution? What if our defintion is different for some reason?
