My understanding is that it was intended to move as much of the system
as possible to building with FORTIFY_SOURCE when we initially imported/
enabled SSP, and that Christos had said as much.

It takes a considerable amount of time to get large sets of source files
building cleanly with FORTIFY_SOURCE because one finds various failures
to conform to the C standard (non-tolerance of standard functions implemented
as macros in header files) and some genuine and sometimes rather complex
bugs (e.g. the struct ifreq problem). My intent was to get as much value
for the initial investment of time as possible.
