Mnph. Illuminating. I have no ideas except for further avenues for
investigation...
Is __unix the only symbol defined in Preprocessor Macros? If not, are
the symbols delimited only by spaces?
What happens if you blank-out Preprocessor Macros and re-enter __unix?
(You've probably done this.)
Examine the build log (force a rebuild and then open the middle split
pane of the "Build -> Detailed Build Results" window) and see if -D
__unix appears in the compiler invocations. (I understand it's broken,
I want to know _where_.)
Have you accidentally overridden Preprocessor Macros in the current
build style (is the entry bold in the build-style listing, or
crossed-out in the target Build settings)? Accidentally setting it,
repenting, and blanking-out the field can result in overriding the
setting to blank, rather than removing the setting from the build
style. You have to press the "-" button to remove the set-to-blank
override (which is a disturbing button to use for the purpose, but I
admit having no better idea).

In the Target build options there is a settings line item called
"Preprocessor Macros". The value is a text field where I had entered
"__unix". I know this was being automagically defined before as
preprocessor conditional code in a header file for different platforms
was correctly defined based off the state of my macro. Simply
updating the project to xcode 1.5 caused the preprocessor conditional
code to be defined incorrectly because "__unix" no longer gets
defined. i.e:
#ifdef __unix
#define DLLOPT
#else
#define DLLOPT __declspec(dllexport) (something that wont naturally
compile on a mac)
#endif
class DLLOPT foo {
public:
}
Again this worked using XCode 1.2. Note I did not change versions of
GCC. When the compiler hits the class definition of foo, it sees the
__declspec(dllexport) garbage in front of the class name implying that
"__unix" is not defined for the scope that file and subsequently
chokes.
