I built rev 68404 on Solaris SPARC and the debugger still fails to launch
the system if the profile has any environment variables set.  I verified
that ecdbgd was compiled today and that the version in

   $ISE_EIFFEL/studio/spec/solaris-sparc/bin/ecdbgd

is identical to the version in

   $EIFFEL_SRC/C/ipc/daemon/ecdbgd

So I believe this isn't fixed yet, at least not on Solaris.
I compiled 68404 using rev 68277.
