automake-1.6.2: bug in nobase.test ?

[Charles Wilson]

On cygwin, I'm failing nobase.test -- which has been expanded in a big 
way between 1.6.1 and 1.6.2.  I expected that there would be problems 
with missing $(EXEEXT) -- but I didn't even get that far(*)  It failed 
in  install-fooexecLTLIBRARIES

...
/bin/bash ./mkinstalldirs 
/usr/src/automake/devel/automake-1.6.2/.build/tests/testSubDir/inst/foo
 /bin/bash ./libtool --mode=install /usr/bin/install -c  sub/libbase.la 
/usr/src/automake/devel/automake-1.6.2/.build/tests/testSubDir/inst/foo/libbase.la
/usr/bin/install -c sub/.libs/libbase.dll.a 
/usr/src/automake/devel/automake-1.6.2/.build/tests/testSubDir/inst/foo/libbase.dll.a
dlpath=`bash 2>&1 -c '. sub/.libs/sub/libbase.lai;echo $dlname'`
dldir=/usr/src/automake/devel/automake-1.6.2/.build/tests/testSubDir/inst/foo/`dirname 
$dlpath`
dirname: too many arguments
Try `dirname --help' for more information.
make: *** [install-fooexecLTLIBRARIES] Error 1
FAIL: nobase.test

The interesting thing is that libtool is trying to access libbase.lai in 
 sub/.libs/SUB/ -- but it's actually in sub/.libs/

Is this an automake bug, or a libtool bug?  (testing on linux worked, so 
I'm guessing that this is a cygwin specific libtool bug in the 
postinstall_cmds)

(*) This looks like a libtool bug, but I wanted to post to automake 
because I *still* think there is going to be a problem with missing 
$EXEEXT in nobase.test, and wanted to 'raise the alarm'...
