rawmemchr: modernize and simplify * lib/rawmemchr.c (HAVE_RAWMEMCHR): Assume it’s not defined; otherwise this file would not be compiled. Include limits.h, stdalign.h, stdint.h, verify.h. (rawmemchr): Prefer uintptr_t to unsigned long and to size_t when it’s the better type. Verify that longword lacks padding. Use alignof rather than sizeof when checking alignment. Simplify by assuming C99 decl-after-statement, and by using multiplication rather than repeated shifting and OR (modern compilers can optimize the multiplication if needed). Avoid unnecessary casts. Don’t assume CHAR_WIDTH is 8. Convert back and forth between void * to suppress bogus GCC warnings about alignment. Omit a duplicate assignment to char_ptr. * modules/rawmemchr (Depends-on): Add stdalign, stdint, verify.
