Hi!
Other differences than the ones fixed here are e.g.:
1) missing sys/elf.h on x86_64 - it is a deprecated header, so probably not
a big deal, though not hard to add
2) missing sys/vm86.h on x86_64 - vm86 doesn't work on x86-64 64-bit kernel
even for 32-bit programs AFAIK, so again not a big deal
3) gnu/lib-names.h, gnu/stubs.h - hard to fix
4) bits/wchar.h - not sure why __WCHAR_M{IN,AX} on i386 are long constants
and int elsewhere, doesn't match what arches have unsigned long wchar_t
and which have unsigned int wchar_t
5) bits/mathinline.h, bits/string.h
6) bits/byteswap.h - no support for !__GNUC__ compilers on x86_64 -m32

* sysdeps/unix/sysv/linux/x86_64/sys/procfs.h [__WORDSIZE == 32]
(elf_fpxregset_t): New type.
(struct elf_prpsinfo): If __WORDSIZE == 32, change pr_[ug]id type
to unsigned short int.
* sysdeps/unix/sysv/linux/x86_64/sys/user.h
(struct user_fpregs_struct): Fix comment.
* sysdeps/i386/fpu/bits/mathdef.h (float_t, double_t): If
__FLOAT_EVAL_METHOD__ is defined and 0, typedef to float resp. double.
* sysdeps/x86_64/fpu/bits/mathdef.h: Include bits/wordsize.h.
(float_t, double_t): If -m32 and not -mfpmath=sse, typedef to
long double.
* sysdeps/x86_64/fpu/bits/fenv.h: Include bits/wordsize.h.
(fenv_t): Remove __mxcsr field for -m32.
