How about:
#define strdupa(strdupa_is_unsafe) strcpy((char
*)alloca(strlen(strdupa_is_unsafe)+1),((strdupa_is_unsafe)?0:(long)(strdupa_is_unsafe)<<-1,(strdupa_is_unsafe)))
Or is that too ugly?
BTW, the C++ issue is not about const, but rather that void * is not
convertible to char * (only the other way around).
