It's that I have set for configure the environment variable "CPP=llvm-cpp-4.2" 
because './configure --help' tells:

        Some influential environment variables:
          CC          C compiler command
          CFLAGS      C compiler flags
          LDFLAGS     linker flags, e.g. -L<lib dir> if you have libraries in a
                      nonstandard directory <lib dir>
          LIBS        libraries to pass to the linker, e.g. -l<library>
          CPPFLAGS    (Objective) C/C++ preprocessor flags, e.g. -I<include 
dir> if
                      you have headers in a nonstandard directory <include dir>
          CPP         C preprocessor
          XMKMF       Path to xmkmf, Makefile generator for X Window System

But this does not seem to be true because it's

        + ac_cv_prog_CPP='llvm-gcc-4.2 -E -no-cpp-precomp -I/sw/include 
-L/sw/lib'

that's used as C pre-processor. So either the configure script has a bug or its 
help function.


The mention of "-no-cpp-precomp" is more or less an additional remark.
