- * hdrmacro.c - handle header files that define macros used in
- *              #include statements.
- *
- *  we look for lines like "#define MACRO  <....>" or '#define MACRO  "    "'
- *  in the target file. When found, we
- *
- *  we then phony up a rule invocation like:
- *
- *  $(HDRRULE) <target> : <resolved included files> ;
- *
- * External routines:
- *    headers1() - scan a target for "#include MACRO" lines and try
- *                 to resolve them when needed
- *
- * Internal routines:
- *    headers1() - using regexp, scan a file and build include LIST
- *
- * 04/13/94 (seiwald) - added shorthand L0 for null list pointer
- * 09/10/00 (seiwald) - replaced call to compile_rule with evaluate_rule,
- *      so that headers() doesn't have to mock up a parse structure
- *      just to invoke a rule.
