-Subject: [PATCH] md5: declare byteReverse as static
-
-byteReverse() is an internal function in md5.c, and is not exposed via
-any header file, but it is not declared as static. This is a problem
-with the md5.c file since it is copied more or less verbatim in other
-programs (fontconfig and pjsip among others), causing a link error
-when linking two of them together.
-
-Fixes link failures such as:
