+Subject: [PATCH] fix builds with newer compilers & C standards
+
+The meaning of "inline" has changed when "static" is not used.
+Since none of these functions are used outside of their respective
+files, mark them as static to avoid build errors where funcs are
+not inlined (based on compiler flags too).
+
+Upstream status: pull request #38
