26 # Adjunct script for GNU CC to populate a directory with ANSI,
27 # Posix.1, and C++ compatible header files.
29 # Each file found under SOURCE-DIR-ALL is analyzed and "fixed."
30 # Only standard ANSI/POSIX files found under SOURCE-DIR-STD
31 # are analyzed and "fixed."
32 # The SOURCE-DIRs are searched in order; a file found
33 # under multiple SOURCE-DIRs is only handled for the first one.
36 # Each include file is fed through cpp, and the scan-decls program
37 # parses it, and emits any found function declarations.
38 # The fix-header program analyzes the scan-decls output,
39 # together with the original include file, and writes a "fixed"
40 # include file, if needed.
42 # The comment at the beginning of fix-header.c lists specifically
43 # what kind of changes are made.
46 # Some file space will be wasted, because the original header
47 # files are copied. An earlier version just included the original
48 # by "reference", using GNU cpp's #include_next mechanism.
49 # This is currently not done, partly because #include_next is
50 # fragile (susceptible to version incompatibilities, and depends
51 # and GCC-specific features), and partly for performance reasons.
54 # Ron Guilmette (rfg@netcom.com) (original idea and code)
55 # Per Bothner (bothner@cygnus.com) (major re-write)
