	Fix scoping in imported modules.

	When handling `import' (`require') statements, mailfromd
	in some cases could have closed and popped the module lexical
	context before finishing processing its actual contents. In
	particular, if a module ended with a variable or constant
	declaration (e.g. status.mf), this declaration would end up
	in the symbol table of the importing compilation unit. This
	happened because yywrap, triggered by EOF on the module unit,
	caused immediate popping of the lexical contents, whereas
	the parser still had some unreduced symbols on its stack. The
	actual reduction (e.g. of the rule `stmt: CONST value') happened
	after the lexer had supplied next symbol, but by that time the
	original module had already been removed from stack.

2009-09-21  Sergey Poznyakoff  <gray@gnu.org.ua>

	Rewrite preprocessing algorithm.

	The internal preprocessor is removed. Inclusion directives
	(#include, #include_once and #require) are handled directly
	in the lexer. External preprocessor is called for each
	input file separately. This gives a lot of advantages:
	  1. The m4 namespace is kept clean. No unwanted m4 definitions
	  propagate between the files.
	  2. No need to fixup input line numbers.
	  3. End of each compilation unit is handled separately,
	  which allows to implement static variables.
	  4. Cleaner code.

2009-08-31  Sergey Poznyakoff  <gray@gnu.org.ua>

	Begin separation of configuration from filter script.

	The purpose is to separate compilation entities (filter script
	and files included therein), from the actual runtime
	configuration.
	This changeset introduces a separate mailfromd configuration file,
	located in SYSCONFDIR/mailfromd.conf. The filter script is called
	mailfromd.mf and located in SYSCONFDIR as well (but perhaps it
	should better be located elsewhere?) The old script name,
	mailfromd.rc, was a misnomer since its suffix suggested that the
	file was a configuration file, which as a matter of fact it was
	not. However, if this "legacy" file is present and readable, it is
	used and a warning message is issued.

	All `#pragma option' statements are considered deprecated,
	and explicit
	warnings are issued if they are used in the script file.

	* NEWS: Update.
	* mfd/appinit.c: New file.
	* mfd/Makefile.am (mailfromd_SOURCES): Add appinit.c

	not from command line or a configuration statement.

	* mfd/main.c (need_config): Rename to need_script.
	(struct option_cache): Rename `cumulative' to `flags'.

	function was called from a pragma option handler.

2009-08-27  Sergey Poznyakoff  <gray@gnu.org.ua>

	Fix diagnostic and help messages.

	1. Option descriptions in `--help' output do not constitute
	   conceptual sentences. Therefore, they should not begin
	   with a capital letter, nor end with a final point.
	2. According to standards.texi, a diagnostic message in a
	   non-interactive program "should not begin with a capital letter
	   when it follows a program name and/or file name, because that
	   isn't the beginning of a sentence.  (The sentence conceptually
	   starts at the beginning of the line.)  Also, it should not end
	   with a period."

	Started major rewrite. The final aim is to make the internal
	program reentrant and to make it stop when it is trying to
	reference a non-existend sendmail variable. Then, the milter
	handler should return SMFIS_CONTINUE to pass control over to the
	next handler. That, in turn, should restart program execution in
	the hope that Sendmail has provided the variable on this stage. If
	it does not the process continues.
