  Modified files:
    contrib/gcc          pexecute.c 
  Log:
  Correct vfork()/exit() to vfork()/_exit().
  
  Also return "1" rather than "-1".  According to bde: -1 is unrepresentable.
  Exit statuses must be >= 0 and <= 255, at least if chars are 8 bits and
  shorts are 16 bits.  This seems to only be documented indirectly in exit.2
  by referring to wait.2.  WEXITSTATUS() throws away all except the low 8 bits
  of the status returned by _exit(), and the kernel actually only stores 8
  bits of it (if chars are 8 bits, etc.), so wait() can't return any more bits.
  
  Obtained from: rev 1.4 of contrib/gcc/gcc.c
