[PATCH] mkancesdirs: Add extern "C" to header

[Simon Marchi]

This is needed when trying to use the module from a C++ program,
otherwise we end up with:

  error: undefined reference to 'mkancesdirs(char*, savewd*, int (*)(char 
const*, char const*, void*), void*)'

ChangeLog:

        mkancesdirs: Add extern "C" to header
        * lib/mkancesdirs.h: Add extern "C".
