# HISTORY
# $Log:	Makefile,v $
# Revision 2.18  91/12/10  16:33:11  jsb
# 	New files from Intel
# 	[91/12/10  16:19:40  jsb]
# 
# Revision 2.17  91/09/04  11:29:10  jsb
# 	Use cc860 for i860.
# 	[91/09/04  11:23:25  jsb]
# 
# 	From Intel SSD: Added I860_CPP for i860 support.
# 	[91/09/02  08:57:36  jsb]
# 
# Revision 2.16  91/08/24  12:32:09  af
# 	Added MACHINE_CFLAGS switch to support the -Wf,-XNk150 flag for
# 	 mips string space. Apparently "danner/n3" is enough longer than
# 	 "dbg" to exhaust string space.
# 	[91/08/21            danner]
# 	Added better cpp technology to deal with gcc limitations. 
# 	      Currently only an issue on luna88k.
# 	[91/07/26            danner]
# 	Made use of -ES vs. -E machine dependent, as luna88k does not
# 	 like -ES.
# 	[91/07/19            danner]
# 
# Revision 2.15.2.2  91/08/21  17:23:08  danner
# 	Added MACHINE_CFLAGS switch to support the -Wf,-XNk150 flag for
# 	 mips string space. Apparently "danner/n3" is enough longer than
# 	 "dbg" to exhaust string space.
# 	[91/08/21            danner]
# 
# Revision 2.15.2.1  91/08/19  13:49:22  danner
# 	Added better cpp technology to deal with gcc limitations. 
# 	      Currently only an issue on luna88k.
# 	[91/07/26            danner]
# 	Made use of -ES vs. -E machine dependent, as luna88k does not
# 	 like -ES.
# 	[91/07/19            danner]
# 
# Revision 2.15  91/07/31  18:32:16  dbg
# 	Directly compile C files if INLINE is null (depends
# 	on the machine).
# 	Remove IBMRT-dependent fiddling for malloc.
# 	[91/07/30  17:32:13  dbg]
# 
# Revision 2.14  91/05/14  17:55:53  mrt
# 	Correcting copyright
# 
# Revision 2.13  91/02/14  14:19:15  mrt
# 	Added new Mach copyright
# 	[91/02/13  12:41:48  mrt]
# 
# Revision 2.12  90/11/05  14:36:32  rpd
# 	Change MACHINE to TARGET_MACHINE.
# 	[90/10/29            rwd]
# 
# Revision 2.11  90/09/09  14:34:39  rpd
# 	Remove call.o
# 	[90/08/24            rwd]
# 
# Revision 2.10  90/06/02  15:13:30  rpd
# 	Compile with -DMACH_IPC_COMPAT=0.
# 	[90/03/26  23:29:39  rpd]
# 
# Revision 2.9  90/05/29  18:40:08  rwd
# 	Fix PMAX_ASFLAGS.
# 	[90/05/22            rwd]
# 
# Revision 2.8  90/05/03  15:54:28  dbg
# 	Use -ES switch to preprocess assembler files.
# 	Not all machines' 'cc' can directly assemble .s files.
# 	[90/04/23            dbg]
# 
# Revision 2.7  90/01/19  14:36:46  rwd
# 	Added call.o
# 	[90/01/03            rwd]
# 
# Revision 2.6  89/12/08  19:53:01  rwd
# 	Use ASFLAGS for assembler, the mips one wants to know which
# 	optimization level the C code was compiled at.
# 	[89/12/06            af]
# 
# 	Changed CFLAGS to remove -g and add -O
# 	[89/10/24            rwd]
# 	Worked over for new merged coroutine-thread version.  Removed
# 	task version.
# 	[89/10/24            rwd]
