[Message part 1 (text/plain, inline)]

Hi,
We build and use libtool for one of the products we are working on.

In the course of build libtool the following was noticed:


1)      Do as usual a configure  --> everything seems fine

2)      export U=abcxyz_idoNotcare_whatitis

3)      make

The make will fail because in the course of its run, it will use a variable called $U.
This bug was noticed when installing libtool 2.4.2 under
Linux-2.6.32-504.el6.x86_64-x86_64-with-redhat-6.7-Santiago
GNU Make 3.81

The fix is clear: Someone must not use U as a variable name.  In this case, the customer was using the variable U as follows:
    export U=~/util
So as a shortcut for their utility directory, which seems to be an admissible use case.

I've not check more recent versions of libtool against this bug.  But as we move away from 2.4.2, it would be not to have to worry about this one.
Thanks.

If you have any further questions, more details can be provided.
Donald
