Re: maintainer-clean and yacc/lex files

[Allan Saddi]

Hi again,

It seems to be present in the CVS version as well, although the
problem is a little different. Neither the generated yacc or lex
C files are removed by maintainer-clean. The yacc .h file is
correctly removed if the -d flag is in (AM_)?YFLAGS.

I don't know perl, otherwise I'd submit a patch, but it looks
like lang_yacc_target_hook does not add the generated yacc
C/C++ file to @maintainer_clean_files. Same for lex.

Also, distcheck fails with "Error: files left after distclean".
It seems that the yacc/lex output files are left in the =build
directory.

My test files are available at:
http://philosophysw.com/am-yacclex-test.tar.gz

If you examine the maintainer-clean target in Makefile.in,
you'll see that parser.c and lexer.c are missing. Attempting a
make distcheck also results in a failure.

Thanks.

- Allan
