packages/net/addrwatch/patches/005-use-c99-format-macro-constants.patch
Jeffery To 31ae85bca9 addrwatch: Various fixes 
Makefile changes include:

* Remove USE_UCLIBC, as uclibc is no longer supported

* Package output modules

* Move main binary (back) to /usr/sbin, as it is system administration
  related and requires superuser privileges

New patches:

* 003-add-space-for-null-byte.patch - from
  374cfd2cab

* 004-more-specific-library-linking.patch - from
  27b57d9da3

* 005-use-c99-format-macro-constants.patch - from
  https://github.com/fln/addrwatch/pull/28

Init script changes include:

* Change from explicit disable to explicit enable, so that the service
  is disabled by default and on first install

* Set config option default values to default values of the main binary

* Fix command-line option names and format (from
  https://forum.openwrt.org/t/cant-start-addrwatch-service/60499/3)

* Always use the --quiet command-line option, as the procd instance is
  not configured to capture stdout/stderr

* Change the syslog config option to start the syslog output module

Subject: [PATCH] Use C99 format macro constants for timestamp and vlan_tag
Since timestamp and vlan_tag in the shm_log_entry struct are C99 fixed
width integer types (uint64_t and uint16_t), the cross-platform way to
print these values is to use the corresponding format macro
constants[1], PRIu64 and PRIu16.
This also adjusts the places where the time_t timestamp value is
printed, casting it to uint64_t, for consistency.
