+Subject: [PATCH] Support building static binaries via --enable-static-binary
+ configure flag
+
+Patch taken from upstream commit
+https://github.com/rvoicilas/inotify-tools/commit/672a3199615e6bbaa9cc788a67ac45213a528971,
+but with only the source code changes kept. The build system changes
+adding the --enable-static-binary is not needed, and not having them
+avoids the need for autoreconfiguring the package.
