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