I hope you are mistaken. Zero Link is a great time-saving feature,
right up there with pre-compiled headers (and multi-core Intel
chips). It's not like new frameworks get incorporated into a
project very often. And recovering from a non-Zero Link linking
error is not that big a deal (just add the framework).
Regarding precompiled headers, in my experience, they are not even
close to being as fast as something like ccache and as far as I was
able to determine when I last looked at it (see the list archives for
my efforts in this direction last year), the two are incompatible
without more work than I was willing to put into it. In addition, the
precompiled header is just a memory dump of the compiler so it is
extremely fragile for use in distributed compilation.
Plus, I can't even begin to imagine how much time I have lost due to
Xcode decided on whim to recompile everything because it decided that
a precompiled header was out of date.
