[Fwd: autoreconf and aclocal options (-I, --ac-dir)]

[Chris Pickett]

I'm resending this to autoconf-patches for consideration in the alpha 
release.  Please CC me, I am not subscribed.  I didn't sign anything 
with the FSF but since it's so utterly trivial you can either reword it, 
or take it from me public domain, if you decide it's worth applying.

I should also add that I have to run autoreconf twice if ACLOCAL_AMFLAGS 
is used to specify the location of the macro dir, but I didn't try with 
the CVS autoconf.

Hi,

I looked at autoreconf and it doesn't pass the dirs of the -I flag on to
aclocal.  The only way for aclocal to get the dirs for -I and --ac-dir
(which, ok, is not for external usage) is by matching
ACLOCAL_[A-Z_]*FLAGS\s*=\s*(.*) in a Makefile.

Assuming this is intentional, perhaps the autoreconf documentation can
be patched as I attached.  This saves the developer that doesn't want to
run aclocal explicitly from having to dig through autoreconf and also
autoconf.info and automake.info.

Cheers,
Chris
