Thu May 9 13:54:49 1996 Roland McGrath <roland@delasyd.gnu.ai.mit.edu>

	* GNUmakefile (globfiles): Add AmigaDOS support files.
	(distfiles): Add $(amigafiles).
	(amigafiles): New variable.

Thu Nov  7 10:18:16 1995  Aaron Digulla   <digulla@fh-konstanz.de>

	* Added Amiga support in commands.c, dir.c, function.c,
	job.c, main.c, make.h, read.c, remake.c
	* commands.c: Amiga has neither SIGHUP nor SIGQUIT
	* dir.c: Amiga has filenames with Upper- and Lowercase,
	but "FileName" is the same as "filename". Added strieq()
	which is use to compare filenames. This is like streq()
	on all other systems. Also there is no such thing as
	"." under AmigaDOS.
	* function.c: On Amiga, the environment is not passed as envp,
	there are no pipes and Amiga can't fork. Use my own function
	to create a new child.
	* job.c: default_shell is "" (The system automatically chooses
	a shell for me). Have to use the same workaround as MSDOS for
	running batch commands. Added HAVE_SYS_PARAM_H. NOFILE isn't
	known on Amiga. Cloned code to run children from MSDOS. Own
	version of sh_chars[] and sh_cmds[]. No dup2() or dup() on Amiga.
	* main.c: Force stack to 20000 bytes. Read environment from ENV:
	device. On Amiga, exec_command() does return, so I exit()
	afterwards.
	* make.h: Added strieq() to compare filenames.
	* read.c: Amiga needs special extension to have passwd. Only
	one include-dir. "Makefile" and "makefile" are the same.
	Added "SMakefile".  Added special code to handle device names (xxx:)
	and "./" in rules.
	* remake.c: Only one lib-dir. Amiga link-libs are named "%s.lib"
	instead of "lib%s.a".
	* main.c, rule.c, variable.c: Avoid floats at all costs.
	* vpath.c: Get rid of as many alloca()s as possible.
