Clang and gcc and includes. A never ending story ;-))

I use:

# Clang trunk
using clang : # version
                3.0
            : # compiler
                $(HOME)/local/bin/clang++
            : # options
                <cxxflags>-fPIC
                <cxxflags>-Wno-mismatched-tags
                <cxxflags>-Wno-unused-variable
                # Workaround
                <cxxflags>-I/usr/include/x86_64-linux-gnu
             ;

The main workaround is -I/usr/include/x86_64-linux-gnu

where  I have

/usr/include/x86_64-linux-gnu/asm/errno.h

You might want to file  a bug report with clang.

Yours,

Jürgen
