25 | # DESCRIPTION | |
26 | # Adjunct script for GNU CC to populate a directory with ANSI, | |
27 | # Posix.1, and C++ compatible header files. | |
28 | # | |
d7943819 PB |
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." | |
7afe1b4d PB |
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. | |
aab7bd19 | 38 | # The fix-header program analyzes the scan-decls output, |
7afe1b4d PB |
39 | # together with the original include file, and writes a "fixed" |
40 | # include file, if needed. | |
41 | # | |
aab7bd19 | 42 | # The comment at the beginning of fix-header.c lists specifically |
7afe1b4d PB |
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 | |
9faa82d8 | 50 | # fragile (susceptible to version incompatibilities, and depends |
7afe1b4d PB |
51 | # and GCC-specific features), and partly for performance reasons. |
52 | # | |
53 | # AUTHORS | |
54 | # Ron Guilmette (rfg@netcom.com) (original idea and code) | |
55 | # Per Bothner (bothner@cygnus.com) (major re-write) | |
