Package: gcc-4.9-base
Version: 4.9.2-10
Debian bug 770025 added a "Breaks: gcc-4.7-base (< 4.7.3)" header to
gcc-4.9, because it was found in bug 736607 (which relates to gcc-4.8)
that the package manager would sometimes leave the system with an
older-release version of gcc instead of using the version from Jessie
(4.7.3 and up).

However, then Debian bug 765379 came around and gcc 4.7 was completely
removed from Jessie.

As a result it is now impossible to keep gcc 4.7 installed on a Jessie
system when upgrading from an earlier release, or to install the package
from an older release, even though absolutely nothing would actually
break as a result of this.
Since the original problem posed in bug 770025 (of the package manager
failing to update gcc-4.7) has been fixed, I believe the "Breaks:
gcc-4.7-base (<4.7.3)" clause should be removed from gcc-4.9 (and
probably from gcc-4.8, too).
