I only said "using gcc as the default compiler".

That is kind of strange.

1. Only the gcc driver is overridden. The compiler is still
there.
2. Install egcs usually means an update. Say my OS has no
compiler, I got a gcc binary and I installed it under /usr/local.
Does egcs do anything to avoid "overwriting" my "default"
compiler?

Install gcc under /usr on linux has been done for years now.
Why a sudden change? For linux users, it will only cause
more confusions since the egcs binary release will be installed
in /usr, not /usr/local. The same goes for glibc, which has
wider impact than gcc. glibc is installed under /usr on linux
unless being told otherwise.
