Yes it should. Defining _GNU_SOURCE should make aligned_alloc visible
regardless of whether -std=c99 is specified. This is because defining
_GNU_SOURCE means, "Make GNU symbols visible even when compiling
pedantically." This is OK, since the C standard says the behavior is
undefined whenever the user defines a reserved symbol like _GNU_SOURCE.

I installed the attached patch into the Emacs master, to try to work
around this problem by putting GCC into C11 mode. Please give it a try.
