I support this plan.
Many of the existing poor-cousin bits of infrastructure date back to a
time when C++ was not a viable candidate for a widely-available tool,
and others, more recent, are conscious imitations of C++ capabilities.
At this point it starts to look a little perverse that we are doing a
half-million-line program in C.
The changes will be low-impact, perhaps even less visible than the
K&R/ANSI C compatibility hacks that we maintained for so long.
A secondary benefit will be that it opens up the use of minor C++
features, without getting us into the C90-vs-99 dilemma that has kept us
from taking advantage of those.

I don't know that it matters that much for GDBserver anymore. When
giant C++ apps like Firefox are running on handheld devices, it's a
little hard to see that a handful of C++ library functions and and EH
data section in GDBserver are going to make it or break it on targets
that people are developing for today. Plus I note that GDBserver is
picking up a load of functionality, and the truly space-conscious are
better-advised to build a custom stub that is stripped down to just the
bits they're going to use.
