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: # If ANSI and POSIX are given, ANSI and POSIX required system
35: # headers are looked for in those subdirectories. These should
36: # normally kust be given as ".", meaning that they can be found
37: # in the source directory directly.
38: #
39: # STRATEGY
40: # Each include file is fed through cpp, and the scan-decls program
41: # parses it, and emits any found function declarations.
42: # The fix-header program analyzes the scan-decls output,
43: # together with the original include file, and writes a "fixed"
44: # include file, if needed.
45: #
46: # The comment at the beginning of fix-header.c lists specifically
47: # what kind of changes are made.
48: #
49: # NOTE
50: # Some file space will be wasted, because the original header
51: # files are copied. An earlier version just included the original
52: # by "reference", using GNU cpp's #include_next mechanism.
53: # This is currently not done, partly because #include_next is
54: # fragile (susceptible to version incompatibilties, and depends
55: # and GCC-specific features), and partly for performance reasons.
