Hi. I am having exactly the same problem. Currently I suspect that  
the reason lies within my Bison version, that is 2.3, and maybe  
within my Flex version, that is 2.5.34. These are the current Bison/ 
Flex versions from the Ubuntu hardy universe.

The rationale to my suspicion derives from the following messages  
that emerge during compilation of llvm 2.2 (gcc 4.2.3):

llvm[2]: Compiling llvmAsmParser.cpp for Release build
/usr/share/bison.simple: In function ‘int llvmAsmparse()’:
/usr/share/bison.simple:614: warning: comparison between signed and  
unsigned integer expressions
/usr/share/bison.simple:626: warning: comparison between signed and  
unsigned integer expressions

llvm[2]: Flexing UpgradeLexer.l
/usr/local/src/llvm-2.2/tools/llvm-upgrade/UpgradeLexer.l:405:  
warning, rule cannot be matched
llvm[2]: Bisoning UpgradeParser.y
/usr/local/src/llvm-2.2/tools/llvm-upgrade/UpgradeParser.y:  
conflicts: 8 shift/reduce, 7 reduce/reduce

I'm going to install older versions (those "officially" supported) of  
the tools and try again.
