Using gcc 5.2 (maybe other versions as well), building mi-pending.c gives these warnings: ./gdb.mi/mi-pending.c: In function ‘thread_func’: ./gdb.mi/mi-pending.c:34:5: warning: ‘return’ with no value, in function returning non-void return; ^ ./gdb.mi/mi-pending.c:38:5: warning: ‘return’ with no value, in function returning non-void return; ^ gdb_compile_pthreads assumes that the build was successful only if there is no output. These warnings therefore make gdb_compile_pthreads think that the build failed, and the test doesn't run. The easy fix is to replace the "return" with "return NULL". I am pushing this as obvious. gdb/testsuite/ChangeLog: * gdb.mi/mi-pending.c (thread_func): Replace return with return NULL.
