Patch: SYS_DARWIN1_3 not set on Mac OS X > 10.0.0

[Colin Simmonds]

Under recent updated versions of Mac OS X (Darwin), the SYS_DARWIN1_3 
define isn't being set because the operating system version reported by 
uname changes with each kernel release, and this propagates up into the 
SYS variable used by the build system.

Under Mac OS X 10.0.3, the SYS variable is reported in Makefile.opts as 
darwin1.3.3, which leads to the compile-time define of SYS_DARWIN1_3_3. 
After upgrading to Mac OS X 10.0.4, the SYS variable becomes darwin1.3.7 
leading to a define of SYS_DARWIN1_3_7 (since Apple for some reason 
incremented the minor version number reported by uname -r by 4 for this 
minor update). Extrapolating back, I imagine similar problems exist 
under 10.0.1 and 10.0.2 and the standalone (non Mac OS X) Darwin 1.3.1 
release as well.

Since the conditional code in vlc for Darwin is controlled by the define 
SYS_DARWIN1_3, this means that none of the Darwin-specific code is hit 
for compiles on any recent release of Mac OS X.

Below is a patch which fixes this problem:

This is only a temporary fix, as it will break again whenever Apple 
increments the version number to 1.4. Longer term, the SYS_DARWIN1_3 
flag should be changed to SYS_DARWIN and the SYS variable set to plain 
darwin without any version numbers at all.
