LARTC - Feb 2004 - tcng version 9l

... is on SourceForge:

http://tcng.sourceforge.net/dist/tcng-9l.tar.gz
md5sum b1dde4ec97fa042d76d498cf87019551

Since I cleaned up so many things for Gentoo yesterday, here''s one
for Debian 3.0. The main problems were:

 - its CPP doesn''t like variadic macros with an empty argument list
 - its CPP really wants -$, even if -std=c99 is set

There was also a race condition beween an exit handler (that had no
business being invoked in the first place) and CPP termination in
tcsim. Funny that this didn''t show up earlier.

Last but not least, there was one more 32 bit-ism I hadn''t caught
yet.

The complete list of changes is below.

----------------------------------- CHANGES -----------------------------------

Version 9l (29-FEB-2004)
------------------------

- configure did not preserve the YACC setting across sessions
- configure now complains if -k, -i, -d, -t, or -y have no argument
- tcc and tcsim now use -$ if -std=c99 does not work (updated tests/cppdollar)
- configure: new options "-$" and "--c99" (or
"-c99") to override dollar
  handling
- the writer helper process of tcsim now always exits with _exit, to avoid
  running the exit handler that kills cpp
- runtests.sh converts " parse " to " syntax " in stderr if
expecting an error,
  because some YACCs print "parse error" instead of "syntax
error"
- examples/prio+fw, examples/tbf, examples-ng/pfifo_fast, examples-ng/prio+fw,
  examples/priority, tests/idiomatic, tests/packet, tests/tcsattpro,
  tests/tcsattpsv, tests/tcsattset, tests/tcsdefinc, tests/trace, tests/u32dlb,
  and tests/u32slb now avoid using variadic macros with an empty argument list
  all, to keep some versions of CPP from complaining
- tests/tcng-7g forced a syntax error at EOF, which yielded inconsistent
  results with different versions of CPP 
- updated kernel version example in tcng/README from 2.4.22 to 2.4.25
- q_htb.c: used ~0UL to mean "0xffffffffUL"
- moved removal of .depend from "clean" to "spotless" make
target
- tcsim/Makefile: removed left-over dependencies on module cleanup targets
  "ephemeral-mod" and "clean-mod"
- tcsim/modules/Makefile did not define OBJS

I still have one more problem with latest Debian unstable. This is the
failure message I am getting:

cc -g -Wall -Wstrict-prototypes -Wmissing-prototypes -Wmissing-declarations

/usr/include/asm/sigcontext.h:79: error: parse error before

/usr/include/asm/sigcontext.h:82: error: parse error before

Which is caused by having klib/include in the include path, and it
overriding what linux/compiler.h is. If I add:

#define __user
#define __kernel

to tcsim/klib/include/linux/compiler.h, everything works perfectly and
tests pass (Passed all 1534 tests (24 conditional tests skipped)).

Sorry for not handling this earlier. Been a bit overloaded recently :-(

I''d rather try to avoid the problem entirely. Fortunately, we can
build tcsim.c without the "kernel" includes.

Please try tcng-9m, and holler if it still doesn''t work.

Thanks,
