25: # DESCRIPTION
26: # Adjunct script for GNU CC to populate a directory with ANSI,
27: # Posix.1, and C++ compatible header files.
28: #
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.
34: #
35: # STRATEGY
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.
41: #
42: # The comment at the beginning of fix-header.c lists specifically
43: # what kind of changes are made.
44: #
45: # NOTE
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
1.1.1.3 ! root 50: # fragile (susceptible to version incompatibilities, and depends
1.1 root 51: # and GCC-specific features), and partly for performance reasons.
52: #

54: # Ron Guilmette ([email protected]) (original idea and code)
55: # Per Bothner ([email protected]) (major re-write)
