   2 # ==========================
   3 # This file is a mod of the stock OTP one.
   4 # The change allows make to stop when a compile error occurs.
   5 # This file needs to go into two places:
   6 #     /usr/local/include/erlang
   7 #     /opt/OTP_SRC/make
   8 #
   9 # where OTP_SRC is a symbolic link to a peer directory containing
  10 # the otp source, e.g. otp_src_R9C-2.
  11 #
  12 # After installing OTP, running sudo make install in otp/build
  13 # will push this file out to the two places listed above.
  14 #
  15 # The mod involves setting the shell variable $short_circuit, which we
  16 # introduce - ie it is not in the stock file. This variable is tested
  17 # to affect execution flow and is also returned to affect the flow in
  18 # the calling script (this one). The latter step is necessary because
  19 # of the recursion involved.
