I wanted to try out llvm-vmkit and followed the steps at this link:
http://vmkit.llvm.org/get_started.html

After checking out llvm and clang, I did a ./configure and make. I get these
errors. /home/ganapathy/projects/llvm is the svn trunk check out. Pasting the
errors below.

/home/ganapathy/projects/llvm/include/llvm/Support/Atomic.h:17:

#include <cmath>
         ^

make[1]: Leaving directory `/home/ganapathy/projects/llvm/lib/Support'

PS: Since this is a fatal build error, I am setting it to release blocker
severity. Not sure how this project uses severity. Thanks
