Bug#777881: Patch for GCC 5 build issue

[Pearson, Greg]

tags 777881 + patch
thanks

Here's a fix for the GCC 5 build issue.  I added "extern" to the callable
copy of the inline functions to ensure externally visible functions are
emitted, please see section "Different semantics for inline functions"
at https://gcc.gnu.org/gcc-5/porting_to.html for more background.
