The LGPL also has additional requirements. You have to distribute the
unlinked object files and the source to the library, so that the recipient
can modify the library and relink.
I believe there are some standard GNU programs that include an exception
similar to the above clause. For instance, programs produced using Bison
contain a copy of a sizable portion of Bison in the yyparse() function.
Bison was originally distributed under the normal GPL, which meant that
anything produced by it was a derived work, and had to be distributed under
the GPL (or something compatible). An exception like Ada's was added to
Bison 1.24.
The info file regarding this exception mentions that GCC has always had
such an exception (an object file produced by a compiler includes large
chunks of code taken verbatim out of tables in the code generator).
