Subject: [PATCH 1/1] configure: fix test-for-synth check with GCC 4.9.0
|
||||||
|
|
||||||
|
With GCC 4.9.0 oprofile 0.9.9 build fails on non-PPC platfroms because
|
||||||
|
the "test-for-synth" configure check result is incorrect: There is a NULL
|
||||||
|
pointer dereference in the test program, so the compiler seems to optimize
|
||||||
|
the rest of the code away, and the test will always succeed regardless
|
||||||
|
whether powerpc_elf64_vec/bfd_elf64_powerpc_vec are present or not.
|
||||||
|
Fix by allocating the referred struct statically.
|
||||||
|
|
||||||
|
While at it, also include stdio.h to avoid a compiler warning.

||||||
