I strongly object. Often -mieee masks real programming errors, like
divisons by zero. I'd rather go for the following strategy: If the
programm is not time critical, and upstream is unwilling to deal with
those problems than -mieee can be added *for that package*. Otherwise
many programms run fine without or the maintainer/upstream is willing
to work those problems out. I've already reported and helped to fix
several packages which could have been "repaired" by using -mieee; and
I do not own an alpha to slow it down with -mieee just because it is
so easy to (not) fix the bugs.
So please contact the package owners in question and check if they are
aware of the problems and/or if fixes are available. Better yet, use
the BTS. In the case of large pieces of code which are only run on
destop style of computers and which are fast moving (e.g. in rapid
developement) -mieee might indeed be sensible.
If you insist on -mieee than set up an autobuilder (e.g. pbuilder or
simmilar) where you can set up specific options like this.
