* sysdeps/i386/elf/start.S (_start): Align stack pointer to
double word boundary before pushing args for main. This way we
don't get penalties for misaligned memory accesses. Reported by
Edward Seidl <seidl@janed.com>.

Besides giving Linus the possibility to change the headers +more freely it has another reason: user level programs now do not +always use the same types like the kernel does. + +I.e., the libc abstracts the use of types. E.g., the sigset_t type is +in the kernel 32 or 64 bits wide. In glibc it is 1024 bits wide, in +preparation for future development. The reasons are obvious: we don't +want to have a new major release when the Linux kernel gets these +functionality. Consult the headers for more information about the changes. + +Therefore you shouldn't include Linux kernel header files directly if +glibc has defined a replacement. Otherwise you might get undefined +results because of type conflicts. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ |
