bug in automake 1.8.3

[James Amundson]

I had a basic Makefile.am that looked like this:

Makefile.am:
----------------------------------------
foo:
        echo "Do not use alt link"
        touch foo 

# dependencies for foo
foo: bar
foo: baz
----------------------------------------

I then needed to modify Makefile.am to allow for different compilation
methods depending on the conditional GCL_ALT_LINK:

Makefile.am:
----------------------------------------
if GCL_ALT_LINK
foo:
        echo "Use alt link"
        touch foo 
else
foo:
        echo "Do not use alt link"
        touch foo 
endif

# dependencies for foo
foo: bar
foo: baz
----------------------------------------

The above Makefile.am worked with automake 1.6.3. With automake
1.8.3, however, I get the following error messages:

----------------------------------------
src/Makefile.am:12: foo was already defined in condition !GCL_ALT_LINK,
which is included in condition TRUE ...
src/Makefile.am:6: ... `foo' previously defined here
src/Makefile.am:13: foo was already defined in condition !GCL_ALT_LINK,
which is included in condition TRUE ...
src/Makefile.am:6: ... `foo' previously defined here
----------------------------------------

I can work around this problem as follows, but I think the above
behavior should be considered a bug.

Makefile.am:
----------------------------------------
foo:
if GCL_ALT_LINK
        echo "Use alt link"
        touch foo 
else
        echo "Do not use alt link"
        touch foo 
endif

# dependencies for foo
foo: bar
foo: baz
----------------------------------------

Thank you for your hard work on automake.
