Comment(by altaic):
Correction: `-isysroot /Developer/SDKs/MacOSX10.5.sdk` is specified in
`aclocal.m4`. I'm not sure why it's there; `-mmacosx-version-min=10.5` is
sufficient to make sure the 10.4 and earlier SDKs aren't attempted, yet
newer SDKs are useable. Apple is also pretty good about supporting
deprecated functions for a couple generations of SDKs, so the 10.6 SDK
should be fine without having to rework anything.
For instance, I just built a new ghc HEAD against 10.6's SDK. I removed
the `-isysroot /Developer/SDKs/MacOSX10.5.sdk` entries from `aclocal.m4`,
ran `make maintainer-clean`, `perl boot`, `./configure --with-macosx-
deployment-target=10.6 --enable-bootstrap-with-devel-snapshot`, and
finally `make -j2`. The build works fine... In fact, the build against
10.6's SDK passed four more tests in the test suite than the previous
build against 10.5's SDK (although I'd since pulled a couple patches).
I no longer have Xcode 3 since Xcode 4 overwrote it, and I haven't yet
been bothered to copy the 10.5 SDK over from an old Xcode 3 pkg. No
worries.
