It strikes me that the Right Thing would be to convince the GCC
maintainers to make that "not a string literal" warning be controlled
by a separate -Wxxx option.  Use of expressions for format specifiers
is a very old C tradition, and IMHO it just doesn't make sense to
start whining about all that code just because the compiler lacks the
wizdom to check its validity.

I tried some time ago to convince the GCC maintainers, but failed.
(Heck, even Ulrich Drepper failed, so I'm in a very good company ;-).
Perhaps if the entire GDB maintenance team bugged them, they would
reconsider...
