* main.c: <stdlib.h> is needed, to introduce the getenv(3)

  prototype declaration.  Without it a C compiler shall infer
  the getenv type as "int getenv(...);", but this is totally
  wrong, especially when your machine's sizeof(int) and
  sizeof(char*) differs.  On such environment a return value
  of getenv(3), which is in fact a char*, might first casted
  into a int (loses data here), and then casted back to char*
  by automatic integral promotion fo fit to the prototype of
  ruby_set_debug_option().
