grub wont compile using gcc 3.3, so i have borrowed a patch from suse for grub 0.93 and edited it so that it will patch cleanly against an already patched gentoo grub 0.92. This should also work for 0.93, if only after a little editing, but I havent tested it. I've only tried booting with 0.92.
Created attachment 12945 [details, diff] patch to get grub to compile using gcc 3.3
http://forums.gentoo.org/viewtopic.php?t=50679&postdays=0&postorder=asc&start=200#357180 I was able to compile Grub-CVS (0.93) on x86 with GCC, by using these CFLAGS: CFLAGS="-minline-all-stringops -Os"
Created attachment 12964 [details, diff] Patch for configure, replaces obsolete -malign= with -falign= When compiling grub 0.92 with either GCC 3.2.2, 3.2.3 or 3.3 (unsure about other versions), this removes the warnings about -malign-functions, -malign-loops and -malign-jumps being obsolete, and replaces them with their modern equivalents, -falign-functions, -falign-loops and -falign-jumps. This removes the need for the -Os configure.in patch (I think? - can someone with GCC 3.3 check that for me; works here without it on GCC 3.2.2).

Sorry about that guys - I kept getting something about a "malformed multipart post" and kept trying again... sincere apologies...
the warnings about -malign-* shouldnt kill the compile. let me paste here what i get for error messages. ayanami root # gcc --version gcc (GCC) 3.3 (Gentoo Linux 1.4, PVR 3.3) Copyright (C) 2003 Free Software Foundation, Inc.

In those errors, the key error would be "fsys_reiserfs.c:115: error: long, short, signed or unsigned used invalidly for `j_mount_id'". So, a patch JUST to get this to compile would (should... i think) only need: diff -urN ./grub-0.92-old/stage2/fsys_reiserfs.c ./grub-0.92/stage2/fsys_reiserfs.c --- ./grub-0.92-old/stage2/fsys_reiserfs.c 2001-10-11 07:14:29.000000000 -0400 +++ ./grub-0.92/stage2/fsys_reiserfs.c 2003-06-08 10:50:45.000000000 -0400 @@ -112,7 +112,7 @@ /* offset in the log of where to start replay after a crash */ __u32 j_first_unflushed_offset; /* mount id to detect very old transactions */ - __u32 long j_mount_id; + __u32 j_mount_id; }; /* magic string to find desc blocks in the journal */ However, the suse patch also did some other cleaning up, like changing the -malign-* to -falign-*, so I figured it couldnt hurt to leave that in. However, it isnt that that is preventing grub 0.92 or 0.93 from compiling using gcc 3.3.
im really not the person for this, 1) I dont use Grub 2) I dont use gcc-3.3 :-) we could use somebody who wants to "do" grub...
