+Subject: [PATCH] autotools: relax soname pattern for dynamic loading
+
+SDL makes assumption that each dynamically loaded library must have
+SONAME matching pattern <libname>.so.<digit>+ hence it discards any file
+that has two (or more) digits after ".so". in practice however SONAME
+might be in the form of ie <libname>.so.<major>.<minor>.
+
+as a solution keep requirement for dynamically loaded files to be named
+<libname>.so.* but consider all the possibilities and prefer the shortest
+one.
+
+Fixes: #289
+From: libsdl-org/SDL#5901
