| Bugfix | |
| * Add printf function attributes to mbedtls_debug_print_msg because we were | |
| not actually getting any printf format specifier warnings prior to this. | |
| Also add extra printf compiler warning flags to builds. | |
| Requirement Changes | |
| * Use %zu for print of type size_t in new work, however please do not use | |
| them in backports, and preferably not in code that needs to be | |
| backported. | |
