Compiler error #40 report

[Stephen Friedl]

/*
 * 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.
