Makefile
###
|
|
### Makefile used to three-stage build a tree of source code. Also used to
|
|
### compile other bundles, first with cc, then with gcc.
|
|
###
|
|
|
|
### This file was written and is maintained by K. Richard Pixley,
|
|
### <rich@cygnus.com>.
|
|
|
|
### Every invocation of this Makefile needs to have a variable set (host),
|
|
### which is the named used for ./configure, and also the prefix for the
|
|
### various files and directories used in a three stage.
|

|
|
### Makefile, and it is not seen if the variable 'host' is not set
