Actually the message is quite clear: The ANSI/ISO C++ committee decided to
fix a bug in the C++ language specification (Personally I didn't like the
old behaviour already more than 10 years ago! ;-).

Thus, what used to be valid code, now has different semantics. egcs
detects old code and provides a work-around for it.

This should not platform dependent and I'm quite sure that with exactly
the same options you're using also he will get the very same warnings.

Unless there is a real compiler bug, that is, but without seeing the
code in question this is impossible to decide.

 o Have the original author use the very same options as you.
 o Possibly have the original author update to egcs 1.0.3 or a current
   snapshot.
 o If he gets the same warnings, his code quite surely is not ISO C++
   compliant and he should fix it.
 o If he doesn't get these warnings or you really believe egcs is in
   error, please provide source code (a minimal example, if possible).

Hope this helps,
Gerald
