Using the multiarch syntax this could be folded into Build-Depends:
That would then cause the gcc-4.5 source to be unpacked to
/usr/src/gcc-4.5/ (I would guess) as part of the installation of
Build-Depends done by sbuild or pbuilder or whatever tool you use.
There would be no special network access required during the build other
than what is already in use for installing Build-Depends in general
prior to a build.
What this really comes down to is patching dpkg / apt / aptitude so they
can "install" sources and sbuild / wanna-build / quinn-diff to cope with
