		     --- The boot/ibm SUBDIRECTORY ---


   Here you will find machine-dependent files for IBM operating systems,
especially the custom.h and defaults.mk files necessary for bootstrapping.
Presently you have your choice of the following machines or compiler
environments (each one of which has its own subdirectory):

	mvs --- Any EBCDIC machine
	pc  --- Any IBM-PC compatible

The IBM RISC-6000 is a Unix machine with an ANSI compiler.  See
boot/unix/ansi for the proper custom.h file.
