Compiler error #40 report

/*
* gccbug.cpp
*
* This little tiny program provokes a compiler bug in GCC "egcs-2.91.66" on
* a RedHat Linux 6.1 system. The C preprocessor output has been stripped down of
* everything that is not necessary to reproduce the bug.
*
* The source code is clearly not valid C++ -- we know this -- but the error
* message asked us to report it. We believe this is not the latest version of
* the compiler, but I was not willing to locate a newer build just to report
* this bug. If the bug doesn't exist in the current version, of course please
* just drop this on the floor. Instead I put my time into making an easy-to-follow
* bug report that lives in a single file and is less than 3000 lines long.
*
* I hope this is helpful.
*
