ICE at an apparently unrelated place

[Wolfgang Bangerth - home account <wolf at gaia dot iwr dot uni-heidelberg dot de>]

Hi again,

another small problem: in the following code snippet, the compiler should
warn about the unknown class X and X::set(), but dies if previously <set>
was included. If the include is omitted, the error message appears as
expected. It seems as if egcs-ss-19980621 gets out of tune somewhere in
<set> and dies at the next possibility.

Apart from these things: great job! The free compilers are evolving faster
than ever and this benefits everyone -- thanks.
Regards
  Wolfgang
