+By default, gcc-5 uses C99 inline semantics, this semantics doesn't 
+generate externally visible function for inline functions. This results in 
+below error, when an another translation unit (TU) tries to link with the 
+inline function,

+| <...>/libuio/0.2.1-r0/git/tools/lsuio.c:85: undefined reference to `uio_mmap'
+| collect2: error: ld returned 1 exit status
+| make[2]: *** [lsuio] Error 1
+-- CUT --
+
+To solve this error and make libuio to compile with both 4.x and 5.x,
+
+1. We can remove 'uio_mmap' inline function definition in uio_mmap.c, and move
+   that definition into uio_helper.h file (which is included by lsuio.c) and 
+   replace inline with "static inline". Similarly it can be done to other 
+   uio_single_munmap and uio_munmap inline functions
+
+2. Add 'extern' keyword in front of inline functions declaration, to make 
+   inlined function as externally visible function, and to link with other TUs.
+
+Going with option 1.
