handle preserving gcov

I have pondered it, yes.

Although it might not be a particularly helpful answer, have you
considered using other tools to get what you want rather than modify
gcov and the runtime code?  You could run the instrumented binary with
(say) one set of options, run gcov, gather the coverage output, and then
merge it into an "accumulated" report that includes what you want.
Repeat.

The main downside is that you have to run gcov over ever source file
after each binary invocation and then process the output.

Cheers, Ben
