I fixed that on the master copy recently.  New releases of GNU
programs should automatically include the change (see below).

Actually, they all are in fact symbolic links to the same copies of
the source code at the MIT AI Lab, but you obviously can't do that in
a distribution tar file.  The reason you see slightly different
versions of various GNU library files is that the distributions of
those different programs were not made all at the same time; thus,
they each got a copy of whatever happened to be the current version at
the time that they were released.  When new versions are released,
they will automagically get the new current versions of the library
files. 

In the case of grep 1.5, Mike wanted to minimize the size of the diffs
from previous versions, so he did not include the current getopt.c, or
update the copyleft messages to use the subroutinized GPL; but that is
an exception . . . .
