/* 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. |
