In autoconf, you don't need to define any of the above.

The variable 'srcdir' means something else in autoconf, and it is 
defined automatically.

The variable 'objdir' will make no sense because you can separate the 
source tree and the build tree by running the 'configure' inside the 
directory obj. (ie: cd obj/ && ../configure)

The variable 'bindir' is also generated for you. But usually you don't 
really need to use it. (I think it is just './')

I guess you got this wrong.

With autotools, you will not be defining 'srcdir' or 'top_srcdir'. One 
way to do things, is to have a Makefile.am in each directory of your 
project. For example, in your projects top directory:

Makefile.am (only one line)
==========================
SUBDIRS = src doc
==========================

in src: Makefile.am
==========================
bindir_PROGRAMS = your_prog_name
your_prog_name_SOURCES = c2vcg.h  dbugh.c  gramcalls.c  gram.y \
scan.l main.c
==========================

Then, you would have one Makefile for *each* subdirectory in your 
project. Those Makefiles will be generated by 'configure' in your 
build tree. When you type make at the 'build' top directory, the 
Makefiles will be called recursively.

'make all' will cause:
make -C src/ all
make -C doc/ all

The variables 'srcdir', 'top_srcdir', 'builddir', etc are defined 
automatically for each Makefile in your building tree. So, for 
src/Makefile, '$(srcdir)' is the same as '$(top_srcdir)/src'


Good luck,
