	* 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>.

 build it manually or with one pass only. You also have to use the

+[Q21]    ``On Linux I've got problems with the declarations in Linux
+           kernel headers.''
+
+[A21] {UD,AJ} On Linux, the use of kernel headers is reduced to a very
+minimum.  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.
