Hello Paul,
I cannot agree with this change:

First, you made a typo, so you are in fact deleting variables with values
starting with a dollar.
Second, the intention to delete all lines matching /^[^=]*=''$/ should be
documented in the comment above the macro.
But I think that we cannot ignore these lines. They mean that the variable
is set to an empty string, right?
For now, I have reverted that change in the CVS.
So the most important question is why LIBS was empty after the first run
of configure -C, while it was unset after the second run?
Nicolas, could you investigate this?
Have a nice day,
Stepan
