Hi folks!

When trying to configure (binutils and gmp, in that case), I'm getting this:
=== snip ===
checking how to run the C preprocessor... /lib/cpp
configure: error: in `/home/luser/Downloads/binutils-2.26.1/libiberty':
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.
make[1]: *** [Makefile:7985: configure-libiberty] Error 1
make[1]: Leaving directory '/home/luser/Downloads/binutils-2.26.1'
make: *** [Makefile:846: all] Error 2
=== snap ===

However, this works as expected:
 printf "#include <stdio.h>\n" | /lib/cpp
It dumps stdio.h and its includes to stdout

What's the issue? Same behavior with binutils and gmp, so I assume autoconf
of gcc as the location of the problem...

You did not tell us what operating system you are using or what compiler is installed. What is the origin of the compiler which was installed?

Does '/lib/cpp --version' or '/lib/cpp -V' produce any useful output?
