        <pre>I am trying build llvm in the source directory itself. I have tar file for
version 3.1.
I get a number of warnings on configuring and finally an error.
Sample of a warning:
---------------------------------------
configure: WARNING: fenv.h: present but cannot be compiled
configure: WARNING: fenv.h:     check for missing prerequisite headers?
configure: WARNING: fenv.h: see the Autoconf documentation
configure: WARNING: fenv.h:     section "Present But Cannot Be Compiled"
configure: WARNING: fenv.h: proceeding with the preprocessor's result
configure: WARNING: fenv.h: in the future, the compiler will take precedence
configure: WARNING:     ## ------------------------------------ ##
configure: WARNING:     ## Report this to <a href="http://llvm.org/bugs/">http://llvm.org/bugs/</a> ##
configure: WARNING:     ## ------------------------------------ ##
---------------------------------------

The error is as follows:
-----------------------------------------------
configure: error: Type int64_t required but not found
-----------------------------------------------

I have used the same source to build llvm earlier and it worked fine. But now i
get an error.

What might be the issue?</pre>
