# DESCRIPTION
|
|
# Adjunct script for GCC to populate a directory with ANSI,
|
|
# Posix.1, and C++ compatible header files.
|
|
#
|
|
# Each file found under SOURCE-DIR-ALL is analyzed and "fixed."
|
|
# Only standard ANSI/POSIX files found under SOURCE-DIR-STD
|
|
# are analyzed and "fixed."
|
|
# The SOURCE-DIRs are searched in order; a file found
|
|
# under multiple SOURCE-DIRs is only handled for the first one.
|
|
#
|
|
# STRATEGY
|
|
# Each include file is fed through cpp, and the scan-decls program
|
|
# parses it, and emits any found function declarations.
|
|
# The fix-header program analyzes the scan-decls output,
|
|
# together with the original include file, and writes a "fixed"
|
|
# include file, if needed.
|
|
#
|
|
# The comment at the beginning of fix-header.c lists specifically
|
|
# what kind of changes are made.
|
|
#
|
|
# NOTE
|
|
# Some file space will be wasted, because the original header
|
|
# files are copied. An earlier version just included the original
|
|
# by "reference", using GNU cpp's #include_next mechanism.
|
|
# This is currently not done, partly because #include_next is
|
|
# fragile (susceptible to version incompatibilities, and depends
|
|
# and GCC-specific features), and partly for performance reasons.
