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

###
### USE OF THIS FILE REQUIRES GNU MAKE!!!
###

### The first versions of the file were written by Rich Pixley (rich@cygnus.com).
### Many subsequent additions (and current maintainance by) david d `zoo' zuhn,
### (zoo@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.

### The variable target may be set for the target of a cross-compilation.

### The variable build may be to build a tree on a machine other than the host.

ifndef host
error:
	@echo You must set the variable \"host\" to use this Makefile ; exit 1
else

### from here to very near the end of the file is the real guts of this 
### Makefile, and it is not seen if the variable 'host' is not set 

### from which cvs tree are we working?
