Correct.  I currently only build the front-end against a built, but not 
installed, LLVM tree with srcdir = objdir.  If you would like to tackle 
this problem and propose a patch, I would be happy to apply it, but I have 
other projects to work on now :)

Here's a new snapshot of the front-end:
http://nondot.org/sabre/2006-03-14-llvm-gcc-4.tar.gz

This:

1. Fixes the inline asm problem you have above.
2. Includes patches to make it better on Alpha's (thanks to patches by
    Andrew Lenharth).
3. Sync's it up with debug info changes in LLVM CVS (by Jim Laskey).
4. Has initial support for target-specific intrinsics, through
    Intrinsics.td.

Please give it a try and let me know if it works any better for you!
