astsa - standalone ast

astsa is a standalone subset of a few popular ast routines.  It
requires iffe(1), <sfio.h> <sfhdr.h> <cdt.h> and the corresponding
libraries.

The source files and headers were filtered through proto(1) for
pre-ansi compatibility.

To build:
	CC=c-compiler-path
	CCFLAGS="c-compiler-flags-with-sfio/cdt-I-dirs"

	iffe -v -c "$CC $CCFLAGS" : run features/ccode
	cp FEATURE/ccode ast_ccode.h
	iffe -v -c "$CC $CCFLAGS" : run features/errno
	$CC -c -I. -Iastsa $CCFLAGS astsa/*.c

Install these headers:
	ast_ccode.h
	ccode.h
	error.h
	option.h
	prototyped.h
