I've had a look at Xcode 3.2.6 (the last release that supports Mac OS X 10.6),
and its <mach-o/getsect.h> *does* include getsectiondata declarations.
Comparing
the 10.5 and 10.6 SDKs included in that release, the function was added in
10.6.
Which Xcode version do you have installed? Maybe you upgraded from 10.5 to
10.6
and forgot to install a corresponding Xcode?
I've also checked cctools on opensource.apple.com and found that it was added
between cctools-758 and cctools-773. However, I've no idea how to determine
which Xcode releases those correspond to.
I have no idea if your workaround patch is the right thing, but given how
difficult it has been to get fixes for older OS X releases upstream, or even
a statement which versions are supposed to be still supported, the way out is
probably to disable darwin10 support in libsanitizer/configure.tgt.
Maybe the Darwin maintainers have some insight?
