The minimum requirements are that you include the license info.
The copyright info also has to be included in some cases, essentially 
for each file that is included in compiled form in a binary package you 
have to reproduce its copyright info if the license requires the 
copyright to be retained in binary distributions.

You can get rid of all the file names. The license info has to be 
included (GPL-2, LGPL-2.1, GPL-3+ with autoconf exception). One can 
argue that the FSF unlimited permission license text (m4/*) also has to 
be included by Policy.

The (L)GPL requires the copyright statements to be included.

I have reduced the given copyright file to a more maintainable version. 
It still keeps some file names (not required) so that one can identify 
the primary copyright holders and the LGPL parts easily.
