(%generic_macro): Use single quotes around literals.
($configure_scan): Define global, and use it instead of the literal.
Use `warn' in place of `printf STDERR'.
functions, no longer use `&' to call functions as it disables
prototype checking, topological sort so that functions are defined
before being used, and put an Autoconf like nice comment to
describe the functions.
(output): Accept an CONFIGURE_SCAN parameters, and open CONF.
(&init_tables): Use them.
* acheaders: Run `autoconf -t AC_CHECK_HEADERS:'$1'' on the fileutils,
and include all these headers in here.
Don't specify `AC_CHECK_HEADERS' as it's the default.

(output_headers): For headers that need to be checked, push either
the specialized macro, or the generic macro call.

(find_autoconf): New, moved some code from the top level.
Use %ENV outside quotes to eliminate a warning.

Factor the simplification of $name.

occurrences where a program/makevar is wanted, register file:line.
Adjust the verbose output.

(scan_c_file): Use b instead of W so that keywords match at
the beginning and the end of the line.
(scan_sh_file): Likewise.
(scan_makefile): Likewise. Use B to match before `-l'.
(output): Suggest AC_CONFIG_HEADER if any C/C++ sources are
found.

Split the line into tokens, and check their validity.

are properly templated, autoheader traces
AC_DEFINE/AC_DEFINE_UNQUOTED. Only literals can be traced, and
actually tracing non literals produces invalid autoheader input.
Hence, provide a means to trace calls to
AC_DEFINE/AC_DEFINE_UNQUOTED with literals.
* acgeneral.m4 (AC_DEFINE_TRACE, AC_DEFINE_TRACE_LITERAL): New
macros.
(AC_DEFINE, AC_DEFINE_UNQUOTED): Use AC_DEFINE_TRACE.
* autoheader.sh: Trace AC_DEFINE_TRACE_LITERAL, not
AC_DEFINE/AC_DEFINE_UNQUOTED.
