cpplib broken with long comments embedded in macros

There was concern that the test case in
http://gcc.gnu.org/ml/gcc-bugs/1999-09/msg00796.html might not be
suitable for inclusion in the gcc test suite (it contained code that
was `merely' GPL, not copyright assigned to the FSF)

Here is a simpler test case that fails against egcs-20000124, and is
not contaminated by any other software.

I hereby place the contents of this article in the public domain.

XEmacs still cannot be compiled by egcs snapshots, due to this problem.
