build failure on Mac OS X 10.5 Leopard

[Adam Mercer]

Hi

I've upgraded my MBP to OS X 10.5 and am having problems building
ioquake3. As Xcode 3 doesn't include the 10.2.8 SDK the
make-macosx-ub.sh script won't work:

[ram at skymoo ioquake3]$ ./make-macosx-ub.sh
/Developer/SDKs/MacOSX10.2.8.sdk/ is missing.
The installer for this SDK is included with XCode 2.2 or newer

so using "make" results in the error:

DED_CC code/qcommon/net_ip.c
code/qcommon/net_ip.c: In function 'NET_GetLocalAddress':
code/qcommon/net_ip.c:758: error: 'OSIOCGIFADDR' undeclared (first use
in this function)
code/qcommon/net_ip.c:758: error: (Each undeclared identifier is
reported only once
code/qcommon/net_ip.c:758: error: for each function it appears in.)
make[2]: *** [build/release-darwin-i386/ded/net_ip.o] Error 1
make[1]: *** [targets] Error 2
make: *** [release] Error 2

this is using SVN r1209

Cheers

Adam
