+Subject: [PATCH] get inline functions work with both gnu11 and gnu89
+
+Upstream-status: Pending
+
+After gcc upgraded to gcc5, and if the codes are compiled without
optimization(-O0),
+and the below error will happen:
+
+./.libs/libnetsnmpagent.so: undefined reference to
`netsnmp_subtree_change_prev'
+./.libs/libnetsnmpagent.so: undefined reference to
`netsnmp_table_dataset_delete_data'
+./.libs/libnetsnmpagent.so: undefined reference to
`netsnmp_subtree_change_next'
+collect2: error: ld returned 1 exit status
+
+gcc5 defaults to -std=gnu11 instead of -std=gnu89, and it requires that
exactly one C
+source file has the callable copy of the inline function. Consider the
following
+program:
+
+ inline int
+ foo (void)
+ {
+ return 42;
+ }
+
+ int
+ main (void)
+ {
+ return foo ();
+ }
+
+The program above will not link with the C99 inline semantics, because no
out-of-line
+function foo is generated. To fix this, either mark the function foo as
static, or
+add the following declaration:
+ static inline int foo (void);
+
+more information refer to: https://gcc.gnu.org/gcc-5/porting_to.html;
+
+but the use of "extern inline" will lead to the compilation issue if gcc is not
+gcc5, so replace inline with "static inline"
