Summary: 7.16.2 fails to compile against Mac OS 10.2 SDK

Initial Comment:
I'm distributing curl for Mac OS X 10.2 and higher, so I'm compiling against the MacOSX10.2.8 SDK on Mac OS X 10.4.9. Compiling bails with the error at the end of this report, with POLLIN, POLLOUT and friends defined both in lib/select.h and <sys/poll.h>.

It looks like the error occurs because HAVE_SYS_POLL_H is set but HAVE_POLL is not, as poll is disabled on OS X. A fix would be only #include'ing <sys/poll.h> if HAVE_POLL is not defined. Or alternatively, just wrap a section of lib/select.h in #ifndef, eg:

#ifndef POLLIN
#define POLLIN 0x01
...
#define POLLRDBAND POLLPRI
#endif

Configure command line:

/Users/vasi/Desktop/xmoto/src/curl-7.16.2/configure --prefix=/Users/vasi/Desktop/xmoto/prefix/10.2

Relevant environment variables:

CC=gcc-3.3
CFLAGS="-Os -isysroot=/Developer/SDKs/MacOSX10.2.8.sdk -arch=ppc -DCURL_DISABLE_NTLM"
LDFLAGS="-Wl,-syslibroot,/Developer/SDKs/MacOSX10.2.8.sdk"
MACOSX_DEPLOYMENT_TARGET=10.2
