+Subject: [PATCH] fstp: Add static to inline functions
+
+From [1]
+"This is needed to avoid a link error where the inline functions appear
+missing at link time.
+From c99 standard inline function should either be declared static or
+have an extern instance in a c file for linking.
+This fix is necessary to build with gcc 7; for some reason it was not
+trigerred before."
