avoid #if inside of rb_str_new_cstr

Browse Source 
ISO/IEC 9899:1999 section 6.10.3 paragraph 11 explicitly states that
"If there are sequences of preprocessing tokens within the list of
arguments that would otherwise act as preprocessing directives, the
behavior is undefined."

rb_str_new_cstr is in fact a macro.  We cannot do this.
