Before Paul's 7fdc3cf, src/alloc.c used to contain a declaration for
aligned_alloc(), which a preprocessor definition turned into
a declaration for hybrid_aligned_alloc().  The preprocessor definition
was redundant as it is contained in src/conf_post.h as well, but the
declaration has to be supplied by some other include file.

(For FreeBSD, stdlib.h, which alloc.c includes, supplies the
declaration, guarded by #if __ISO_C_VISIBLE >= 2011 || __cplusplus >=
201103L, which is true by default, at least on FreeBSD 10).
