+Subject: GCC-10 compatibility patch
+
+* Add `-fcommon` to most gcc invocations to allow duplicate definitions
+* __builtin_strlen seems to fall back to calling strlen if the string in
+  question is not const and cannot be evaluated at compile time. Work
+  around the issue by supplying an inline function. The strlen function
+  was copied from com32/lib/strlen.c.
