That is unfortunate.  We have said for over a year that 10.0 should not ship with gcc.  I can delay committing the patch to flip the switch until later in the code slush, if re approves, but ports that require gcc should be building with gcc from ports (which will also improve code quality, as gcc 4.6/7 produce significantly better code than 4.2.1).
