It is one thing to ignore them when compiling the compiler with the
warning flags "-W" and "-Wall" raised  but: !!

I thought the rebuilding under v2.02 was completed when the size of
the installed executables stabilized.  However, when the new "gcc"
is used to build another program, in this case infozip's zip 2.3k
screen after screen of similar warnings are issued even without the
warning flags raised.  See below.  Since the released binaries do
not behave this way there is something which has gone wrong in the
build.  These warnings cannot be ignored.  If allowed to continue
it could undermine the faith of a whole generation of programmers
in the orthogonality of the standard header files.

and so on for 186 more lines
; - - - - end of zip-err.281

The program "zip.exe" seems functional.  Not at all unusual in size or
speed so the rebuilt gcc is working.
