/* This is an example of a header file for platforms/compilers that do
 * not come with stdint.h/stddef.h/stdbool.h/string.h. To use it, define
 * PB_SYSTEM_HEADER as "pb_syshdr.h", including the quotes, and add the
 * extra folder to your include path.
 *
 * It is very likely that you will need to customize this file to suit
 * your platform. For any compiler that supports C99, this file should
 * not be necessary.
