-Subject: [PATCH] Fix linking with boost 1.75.0
-
-Boost 1.75.0 has a bug that causes "multiple definitions" errors in the
-linking stage. This was fixed in later versions by declaring some
-functions as inline.
-
-See https://github.com/boostorg/safe_numerics/issues/106 .
-
-As a (ugly) workaround, override the function that breaks kdiff3's build
-to be inline before including the boost headers (when using 1.75.0).
