That's unfortunate but good to know that it doesn't output both or a
means to dynamically select it after running automake. That being the
case, I'm wondering if there is something that I can do at autogen.sh
time instead (which runs either autoreconf if it can or all the steps
individually if autoreconf fails).
Is there a way to pass "no-dependencies" to automake through
autoreconf? I of course could automatically edit the configure.ac
depending on the existence of CVS directories to uncomment/comment the
line or even just directly edit the AM_INIT_AUTOMAKE options to add the
no-dependencies option. That is less than desireable, though, for
various hopefully evident reasons.
Alternatively, I should be able to run automake again after autoreconf
completes and directly pass the no-dependencies option, perhaps
requiring a run of config.status --recheck too? Thanks again for the
help and suggestions.
Cheers!

I think that this option tells automake to generate different
Makefile.in,
which is horter and doesn't include the code for dependency tracking.
As the Makefile.in is distributed in the tarball, you cannot have both
versions in one tarball. Thus you have to decide at the time when
automake is run, not when configure is run.
You can use m4 conditions to achive what you want; for example:
dnl Uncomment this to get a distribution tarball:
dnl m4_define([foo_distrib])
AM_INIT_AUTOMAKE(m4_ifdef([foo_distrib], [[no-dependencies]])
or, if your CVS (non-production) versions have a specific version
number,
say they end with a letter:
m4_define([foo_version], [1.2.3a])
AC_INIT([Foo], foo_version, [EMAIL PROTECTED])
AM_INIT_AUTOMAKE(m4_bmatch(foo_version, [[a-z]$], [[no-dependencies]]))
I haven't tested these examples, but I hope they'll help you anyway.
=== A different kind of answer:
With gcc, the dependency info is generated as a side effect of the
compilation. If you can use gcc, you might find out that the speedup
is not worth all these complications.
Have a nice day,
