When /bin/sh is a symlink to /sw/bash, bash sees "/bin/sh" as the name
it is invoked with--so it *is* running in sh compatibility mode. The
problem's we're seeing aren't with bash, but with zsh--in this case
there's an error in the code, and an error in zsh, and the two wrongs
happen to make a right. With bash, we only see the error in the
code--but it's *correctly* finding this error.
The three problems that I brought up aren't relevant to bash on other
distros. On other distros they don't try to execute system(";") since
they're used to it failing; they don't use "(foo|bar)" syntax, since
nothing but zsh supports it; and they don't use Darwin's archive_cmds,
so that doesn't break.
Switching to bash is sort of like switching to -shlibs. It creates some
problems initially just because it's slightly different from what we're
used to, and we need to adjust. But there's nothing intrinsically wrong
with it, and after we change a couple of things everything should work
fine.

That's quite surprising. Did you try building any of the packages I
listed? It would be quite surprising if bash was emulating zsh's broken
implementation of 'test'.
