implement "low hanging fruit" from C11 based on Gregor's patch sent to the list. includes: - stdalign.h - removing gets in C11 mode - adding aligned_alloc and adjusting other functions to use it - adding 'x' flag to fopen for exclusive mode 2012-08-25 23:15:13 -04:00			`#include <stdlib.h>`

move core memalign code from aligned_alloc to __memalign there are two motivations for this change. one is to avoid gratuitously depending on a C11 symbol for implementing a POSIX function. the other pertains to the documented semantics. C11 does not define any behavior for aligned_alloc when the length argument is not a multiple of the alignment argument. posix_memalign on the other hand places no requirements on the length argument. using __memalign as the implementation of both, rather than trying to implement one in terms of the other when their documented contracts differ, eliminates this confusion. 2013-07-04 23:58:16 -04:00			`void *__memalign(size_t, size_t);`
