C++ support (6)

[Bruno Haible]

To avoid C++ name mangling of the exported symbols, I applied this.

2006-11-03  Bruno Haible  <address@hidden>

        * lib/c-ctype.h [C++]: Define functions without name mangling.
        * lib/fwriteerror.h [C++]: Likewise.
        * lib/gcd.h [C++]: Likewise.
        * lib/linebreak.h [C++]: Likewise.
