24: # DESCRIPTION
25: # Adjunct script for GNU CC to populate a directory with ANSI,
26: # Posix.1, and C++ compatible header files.
27: #
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.
33: #
34: # STRATEGY
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.
40: #
41: # The comment at the beginning of fix-header.c lists specifically
42: # what kind of changes are made.
43: #
44: # NOTE
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.
51: #
52: # AUTHORS
53: # Ron Guilmette ([email protected]) (original idea and code)
54: # Per Bothner ([email protected]) (major re-write)
