Yes, it does require recompiling to rebuild *.o files and executables.
Though that isn't a full build, it can take quite some time. On my aging
desktop, 'configure' takes 58 seconds, and the followup 'make' takes 61
seconds.
There is a tradeoff between speed and correctness, since 'configure' can
change Makefiles, which means a full rebuild might be needed no matter
what. But you're right, the change I installed was probably too
aggressive for typical use. So I changed 'configure' back, so that it no
longer removes *.o and dependency files. This means Robert Marshall will
probably have to do a full rebuild by hand.

That solution wouldn't have worked for this particular problem even if
we were still using Automake, as the dependencies in question were not
generated by GCC or by Automake. Sometimes after a big change, one must
simply do the full './autogen.sh; ./configure; make' dance, as our
default shortcuts are not safe in general.
