   2 ### Makefile used to three-stage build a tree of source code.  Also used to
   3 ### compile other bundles, first with cc, then with gcc.

   6 ### This file was written and is maintained by K. Richard Pixley,
   7 ### <rich@cygnus.com>.

   9 ### Every invocation of this Makefile needs to have a variable set (host),
  10 ### which is the named used for ./configure, and also the prefix for the
  11 ### various files and directories used in a three stage.
  12
  13 ifndef host
  14 error:; @echo You must set the variable \"host\" to use this Makefile ; exit 1
  15 else
  16
  17 ### from here to very near the end of the file is the real guts of this
  18 ### Makefile, and it is not seen if the variable 'host' is not set

  32 ### then set the macro to be empty.

  35 ### The name of the cvs module for this release.  The intersection of
  36 ### CVS_MODULE and CVS_TAG defines the source files in this release.

  46 ### With luck, eventually, nothing else will need to be editted.
