Summary: libgphoto2 compilation issues on MacOS X

Initial Comment:
I am compiling libgphoto2 on MacOS X 10.5

libgphoto2_port/serial/unix.c uses the macro O_NDELAY which is not defined for POSIX code (I mean, in MacOS X include files, I have not verified this for real POSIX compliance). I replaced it with O_NONBLOCK to continue compilation.

Some source files in the camlib use u_char which is also not defined for POSIX code in the include files. To override strict POSIX compliance, I have added the following code in ibgphoto2_port/gphoto2/gphoto2-port-portability.h after the definition of _POSIX_C_SOURCE

#ifdef __APPLE_CC__
#define _DARWIN_C_SOURCE
#endif

Cf http://developer.apple.com/releasenotes/Darwin/SymbolVariantsRelNotes/index.html#//apple_ref/doc/uid/TP40006658-DontLinkElementID_4 for some explanation on the _DARWIN_C_SOURCE macro.

This is a quick and dirty workaround, but it worked to compile the library to the end ; I guess that a correct implementation should use a macro in config.h set by the configure script.

I dont get the one about DARWIN_C_SOURCE though.
