#
# DESCRIPTION
#	Adjunct script for GNU CC 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 incompatibilties, and depends
#	and GCC-specific features), and partly for performance reasons.
