Can't compile efi-amd64 on x86

[Lukas Anzinger]

Hi,

I branched the latest revision from the Bazaar repository and wanted
to compile it for EFI-amd64:

###
$ ./configure --prefix=/usr --includedir=\${prefix}/include
--mandir=\${prefix}/share/man --infodir=\${prefix}/share/info
--sysconfdir=/etc --localstatedir=/var
--libexecdir=\${prefix}/lib/grub2 --disable-maintainer-mode
--disable-dependency-tracking --enable-grub-mkfont --with-platform=efi
--target=amd64-pe
$ make
[...]
In file included from ./lib/minilzo/lzoconf.h:75:0,
                 from ./lib/minilzo/minilzo.h:60,
                 from fs/btrfs.c:29:
./lib/minilzo/lzodefs.h:849:6: error: #error "this should not happen"
###

The line 849 from lzodefs.h:

###
841 #if (LZO_ARCH_I386)
842 #  if (UINT_MAX != LZO_0xffffL) && defined(__i386_int16__)
843 #    error "this should not happen"
844 #  endif
845 #  if (UINT_MAX != LZO_0xffffffffL) && !defined(__i386_int16__)
846 #    error "this should not happen"
847 #  endif
848 #  if (ULONG_MAX != LZO_0xffffffffL)
849 #    error "this should not happen"
850 #  endif
851 #endif
###

So it looks like LZO_ARCH_I386 is defined although it shouldn't be
since I want to compile an efi-amd64 version. The configure command
works with the latest official release 1.99 (as well as ~rc2):
everything compiles correctly. I think it's due to the change of the
LZO library.

I can also reproduce the problem if I want to compile the file "manually":

###

./lib/minilzo/lzodefs.h:849:6: error: #error "this should not happen"
###

If I add "-m64" to the gcc call, it compiles correctly. This looks
like an error in the build system to me, however, I don't have any
experience with GNU autotools.

Maybe somebody can take a look at it.
